        patch from [e-mail] (Chris Faylor):
        * console.cc: Add convenience macros and structures for handling
        scrolling.
        (fhandler_console::fillin_info): New function to fill in the `info'
        struct.
        (fhandler_console::scroll_screen): Change to scroll only the visible
        portion of the screen.  Honor scroll regions more stringently.
        (fhandler_console::open): Use new fillin_info function.
        (fhandler_console::ioctl): Use new fillin_info function which
        automatically calculates screen size.
        (fhandler_console::clear_screen): Use new fillin_info function.
        Only clear visible portion of screen.
        (fhandler_console::cursor_set): Add a flag to indicate whether
        cursor positioning is absolute within buffer or is screen relative.
        Use new fillin_info function to get screen information.
        (fhandler_console::cursor_rel): Use new fillin_info function.
        Change for new cursor_set parameter.
        (fhandler_console::cursor_get): Use new fillin_info function.
        (fhandler_console::char_command): Use new fillin_info function
        where appropriate.  Change for new cursor set parameter where
        appropriate.  Scroll only visible portion of screen when required.
        * fhandler.h (class fhandler_console): Add fillin_info, change
        cursor_set to reflect additional argument.

Mon Nov 10 15:11:42 1997  Geoffrey Noer  <[e-mail]>

	patch from [e-mail] (Chris Faylor):
        * dcrt0.cc (dll_crt0_1): Register process start time.
        * fork.cc (cygwin_fork_helper1): Register process start time.
        * utils/ps.cc (main): Report process start time.
        (start_time): New function to format time similarly to UNIX ps.
        A time from today shows as HH:MM, times from previous days just
        show the month and day.
        * winsup.h (class pinfo): Add start_time field.

Mon Nov 10 11:54:27 1997  Ian Lance Taylor  <[e-mail]>

        * include/Windows32/Defines.h (TIME_ZONE_ID_INVALID): Define.
        * times.cc (gettimeofday): The error return from
        GetTimeZoneInformation is TIME_ZONE_ID_INVALID, not
        TIME_ZONE_ID_UNKNOWN.

Sun Nov  9 17:08:30 1997  Geoffrey Noer  <[e-mail]>

	patch from [e-mail] (Chris Faylor):
	* Makefile.in: add ../libiberty/strsignal.o
	* cygwin.din: add exports for strsignal, strtosigno
	* utils/kill.cc: changes to allow accepting signal name
	as argument

Sun Nov  9 17:08:30 1997  Geoffrey Noer  <[e-mail]>

	* include/limits.h: define PATH_MAX here instead of
	include/sys/param.h, define _POSIX_NGROUPS_MAX as 0 not 1
	(system invariant value, not implementation-specific)
	* include/sys/param.h: remove PATH_MAX, change NOFILE from 64
	to 8192, delete PATHSIZE, remove safety wrapper around
	MAXHOSTNAMELEN, add comments
	* sysconf.cc (sysconf): return NGROUPS_MAX not zero,
	return _POSIX_SAVED_IDS not zero.  Return _POSIX_CHILD_MAX
	not 4096.  Return _POSIX_CHILD_MAX, not 8.

	patch from [e-mail] (Sergey Okhapkin):
	* winsup.h: add proto for setdtablesize, define NOFILE_INIT
	and NOFILE_INCR
	* hinfo.cc (hmap_init, hinfo_vec::find_unused_handle): change to
	support virtually unlimited numbers of fds.  Remove setdtablesize
	proto
	* syscalls.cc: initialize dtable_size to NOFILE_INIT instead of
	NOFILE

Thu Nov  6 13:14:09 1997  Geoffrey Noer  <[e-mail]>

	* exceptions.cc (__cygwin32_exception_handler): don't
	print "In cygwin32_except_handler" for exceptions Cygwin32
	isn't going to handle.  Print "(progname PID) Exception: <type>"
	to console.  Redirect all detailed information including the
	stack trace to <progname>.core.  This should reduce confusion
	about what's causing the exception (a lot of people would see "In
	cygwin32..." and think the problem was in Cygwin32 when most of
	the time it was in some other program).
	* syscalls.cc: add fixme
	* times.cc: add fixme

Wed Nov  5 19:23:10 1997  Geoffrey Noer  <[e-mail]>

	patch from [e-mail] (Chris Faylor):
	* Makefile.in: force .c.os and .cc.os to be built in same
	directories as source

Wed Nov  5 19:23:10 1997  Geoffrey Noer  <[e-mail]>

	* drct0.cc (dll_crt0_1): stop initializing winsock on process
	startup since that slows down startup time of all processes, even
	ones that don't end up making Winsock calls.
	* fork.cc (cygwin_fork_helper1): don't need to call uinfo_init
	or socket_checkinit after fork -- the appropriate functions will
	do the necessary initialization if they are ever called.
	* net.cc: init winsock_init_p to zero and make it static
	(all exported functions): call winsock_init before making
	any WinSock calls since this no longer happens in dcrt0.cc
	startup code.  Only do this if !winsock_init_p.
	(winsock_init): checkinit renamed.  Now just inits winsock
	without checking whether it has been already initialized.
	Make it static.
	* uinfo.cc (uinfo_init): after we call getpwnam, we know
	the passwd file has been read in so don't check initialization
	of it.  However, we do need to read_etc_group() if group_in_memory
	isn't set.
	* passwd.cc: rename global i variable to pw_pos, rename
	passwd_in_memory to passwd_in_memory_p to match net.cc scheme.
	Add comments.
	(read_etc_passwd): make static
	(various): make sure to read_etc_passwd() if passwd_in_memory
	isn't set
	* grp.cc: add comments, rename idx global to grp_pos,
	rename group_in_memory to group_in_memory_p to match net.cc
	scheme, group_in_memory_p no longer static (needs to be accessed
	by uinfo_init)
	* winsup.h: remove proto for socket_checkinit since that's
	renamed and static within net.cc

Tue Nov  4 01:02:20 1997  Geoffrey Noer  <[e-mail]>

	patch from [e-mail] (Chris Faylor):
	* signal.cc (sigprocmask): Newer versions of gcc will call
	sigprocmask when a builtin constructor is activated.  If this
	happens prior to the setup of u->self, then a NULL dereference
	will occur.  Guard against this.

Mon Nov  3 17:00:45 1997  Geoffrey Noer  <[e-mail]>

	patch from [e-mail] (Chris Faylor):
	* hinfo.cc (hinfo_vec::build_fhandler): Open a console for
	/dev/tty when !use_tty.

Thu Oct 30 10:28:15 1997  Tom Tromey  <[e-mail]>

        * include/mapi.h: New file.
        * sysdef/i386/mapi32.def (MAPISendMail@20): New export.

Thu Oct 30 15:08:13 1997  Geoffrey Noer  <[e-mail]>

        * times.cc: add comments listing standards funcs are defined in
	(dump_filetime): remove unused local func
        * net.cc (fail): remove local func, replace one reference with
        equivalent debug_printf, add standards comments, reformat a little
        (fhandler_socket::close): simplify handling of res
        (fhandler_socket::fstat): set ENOSYS (unimplemented)
        * stubs.cc: set ENOSYS in unimplemented funcs
        * uname.cc: add standards comment
	* ntea.cc: reformat

Wed Oct 29 22:43:57 1997  Geoffrey Noer  <[e-mail]>

	* times.cc (settimeofday): set ENOSYS instead of EPERM
	since ENOSYS maps to "Function not implemented" which is the
	case here.
	* syscalls.cc (seterrno): on failure, set EACCES instead of EPERM
	which is better for the unknown error case

Fri Oct 24 01:24:07 1997  Geoffrey Noer  <[e-mail]>

	patch from [e-mail] (Anthony Green):
	* dcrt0.cc: new host_dependent_constants object with a global
	instance of it which allows constants that are different in Win 95
	and NT to be saved here instead of having forks in the code and
	having to check the OS type each time.  Add two constants for
	fhandler, one for sharing attributes and one for upper word value
	for locking files.
	(dll_crt0_1): call host_dependent init function
	* fhandler.cc (fhandler_base::open): use above object for
	setting shared attributes
	(fhandler_disk_file::lock): get upper word for locking from
	host_dependent_constants
	* winsup.h: define host_dependent_constants class and add extern
	for global instance of it

Wed Oct 22 02:27:53 1997  Geoffrey Noer  <[e-mail]>

	patch from [e-mail] (Sergey Okhapkin):
	* cygwin.din: Export getenv, putenv, setenv and unsetenv instead
	of cygwin32_ wrappers
	* dcrt0.cc: External variable environ removed
	(dll_crt0_1): strip executable's path on console title if
	environment variable CYGWIN_TITLE set to "strip", references to
	environ removed.
	* environ.cc: New file. Code derived from newlib sources.
	* exec.cc: include stdlib.h
	(execl, execv): new (derived from newlib sources).
	(sexecve): reference to environ removed.
	(sexecvpe): call getenv instead of cygwin32_getenv.
	* grp.cc: new static variable group_in_memory
	(read_etc_group): skip blank lines
	(getgrgid, getgrnam, getgrent): call read_etc_group when necessary.
	* misc.cc (cygwin32_getenv/putenv/setenv/unsetenv): remove
	wrappers.
	* passwd.cc: new static variable passwd_in_memory
	(read_etc_passwd): skip blank lines
	(search_for, getpwent): call read_etc_passwd when necessary.
	(setpwent): fixed incorrect initialization of i var.
	* pinfo.cc (pinfo_init): initialize uid with illegal value to
	force read of /etc/passwd and /etc/group.
	* spawn.cc: call getenv instead cygwin32_getenv
	(spawn_guts): force read of /etc/passwd and /etc/group on sexec
	calls.
	* uinfo.cc (uinfo_init): read /etc/passwd and /etc/group only if
	uid is undefined.
	* winsup.h: remove protos for environ, cygwin32_getenv,
	cygwin32_putenv

Wed Oct 22 02:08:54 1997  Geoffrey Noer  <[e-mail]>

	* utils/aclocal.m4: new file.  Define autoconf macros for
	determining whether we're compiling for the cygwin32 environment
	or not and determine the executable suffix
	* utils/configure.in: call AM_CYGWIN32 and AM_EXEEXT
	* utils/configure: regenerate
	* utils/Makefile.in: add $(exeext) after executable names so
	programs will be built with the .exe suffix

Wed Oct 22 00:50:27 1997  Geoffrey Noer  <[e-mail]>

	Now that it is possible to use gdb using a stable
	cygwin.dll to debug a program using a newer, potentially buggy
	cygwin.dll, the strace mechanism will probably end up being
	used more and more for debugging timing/race-condition bugs that
	aren't easily exposed in a gdb session.  The following changes
	make the strace facility better for debugging timing issues by
	storing the last few commands in a buffer instead of writing
	to disk each function call.

	patch from [e-mail] (Chris Faylor):
	* dcrt0.cc (dll_crt0_1): Change to strace_init call to take
        an argument (for planned future registry changes).
        (_exit): Call strace_dump when appropriate.  Add a debugging
	printf.
        * include/sys/strace.h: Add _STRACE_CACHE, _STRACE_EXITDUMP,
	strace_dump ().
        * strace.c (strace_init): Allow hexadecimal, octal setting of
        strace flags in environment variable.  Handle new cache option.
        (strace_printf): Display number of seconds from last message.
        Handle _STRACE_CACHE.
        (strace_dump): New function.  Dump cached messages to disk.

Wed Oct 22 00:08:40 1997  Geoffrey Noer  <[e-mail]>

	* cygwin.din: export socket calls without cygwin32_ prefix
	* net.cc: remove unused herror function in favor of
	cygwin32_herror	which is exported as herror
	* include/netdb.h: we are now exporting the socket calls without
	the cygwin32_ prefix so we don't need the nasty remapping in
	header files
	* include/arpa/inet.h: ditto
	* include/sys/socket.h: ditto
	* select.cc (select): make extern C

Tue Oct 21 22:52:29 1997  Geoffrey Noer  <[e-mail]>

	patch from [e-mail] (Chris Faylor):
	* sigproc.cc (sigproc_terminate): Fix flawed attempt to signal
        any processes waiting for signal notification success when the
        process receiving the signal is terminating.
        (wait_subproc): Report on errors when opening the
	sync_proc_subproc mutex.  Move initialization of events[0]
	"wakeup" signal prior to wait_subproc_inited or risk a (miniscule)
	chance for a reference to a NULL handle.
        * strace.cc (ta[]): Change WM_ASYNCIO entry to reflect previous
        changes to WM_ASYNCIO constant.

Tue Oct 21 14:30:14 1997  Geoffrey Noer  <[e-mail]>

	patch from [e-mail] (Chris Faylor):
	* sigproc.cc (proc_subproc): fix minor error output problem

Mon Oct 20 20:19:02 1997  Geoffrey Noer  <[e-mail]>

	* Makefile.in: change DLL_NAME to cygwin97r2.dll

Mon Oct 20 20:16:47 1997  Geoffrey Noer  <[e-mail]>

	patch from [e-mail] (Sergey Okhapkin):
	* window.cc (alarm): When there is a previous alarm() request
	with less than one second remaining, then the return from a call
	to alarm() is supposed to return 1.

Mon Oct 20 20:16:47 1997  Geoffrey Noer  <[e-mail]>

	patch from [e-mail] (Chris Faylor):
	* Makefile.in: Add sigproc.o target.  Add sigproc.h dependency
	where appropriate.  Add -s to intermediate ld of cygwin.dll to
	speed up the process of building the .dll.
	* dcrt0.cc: Add new sigproc.h include.
	(dll_crt0_1): Replace window_init with sigproc_init for
