Sun Oct 27 22:28:00 1996  J. Richard Sladkey  <[e-mail]>

	* util.c (umovestr) [LINUX]: Handle Linux like SunOS4
	instead of SVR4.  That is, read a few bytes at a time
	to avoid overrunning the end of the stack.

Fri May 31 01:48:49 1996  J. Richard Sladkey  <[e-mail]>

	* version.c: Version 3.1 is released.

Thu May 23 01:04:43 1996  J. Richard Sladkey  <[e-mail]>

	* aclocal.m4 (AC_DECL_SYS_ERRLIST): Try looking in stdio.h
	as well since that's where glibc declares it.  Go figure.
	* signal.c (sys_sigreturn) [ALPHA]: Use sigcontext
	instead of sigcontext_struct since glibc v5+ apparently
	plays games with the native OS namespace.
	From David Mosberger-Tang <[e-mail]>.

Mon May 20 23:17:14 1996  J. Richard Sladkey  <[e-mail]>

	* version.c: Version 3.0.14 is released.

	* aclocal.m4 (AC_STRUCT_MSG_CONTROL): New macro.
	* configure.in: Add call to AC_STRUCT_MSG_CONTROL.
	* net.c (printmsghdr): Handle BSD 4.3 and 4.4 msghdr members
 	differently.
	Reported by Henrik Storner <[e-mail]>.

	* configure.in: (AC_CHECK_{HEADERS,FUNCS}): Add checks for
 	sys/filio.h and sys/stream.h and remove check for poll.
	* desc.c (decode_select, sys_select, sys_oldselect) [LINUX]:
 	Handle old and new styles of argument passing for select on Linux.
	* ioctl.c, stream.c: Conditionalize stream code on presence of
	sys/stream.h instead of poll because glibc implements poll but
	not the rest of the stream interface.
	* signal.c [LINUX]: Standardize on the name sigcontext_struct.
	(sys_sigprocmask) [ALPHA]: Handle OSF flavor which is more like
	sigsetmask.
	* term.c (term_ioctl): Use _VMIN, if present, for TC{G,S}ETA*.
	* util.c (umoven, umovestr): Move data in long-sized chunks
	at a time, instead of hard coding it to be 4.
	From David Mosberger-Tang <[e-mail]>.

Mon May 20 01:19:36 1996  J. Richard Sladkey  <[e-mail]>

	* version.c: Version 3.0.13 is released.

	* configure.in (AC_CHECK_HEADERS): Add check for asm/sigcontext.h.
	* signal.c [HAVE_ASM_SIGCONTEXT_H]: Conditionally include
	asm/sigcontext.h to define sigcontext_struct and don't define it
	locally if the header is present.

	* syscall.c (nerrnos{0,2}): Correct size computation.

	* Makefile.in: Remove dependencies and rules relating to files
 	normally found in the os directory.  Because of the new scheme we
 	don't know precisely where they come from.  Sigh.
	* signalent.sh: Make it work for sunos4, linux, and svr4.
	* {sunos4,linux{,/alpha},svr4}/Makefile.in: Make rules correspond
 	to traditional make syntax.  Add signalent.h to files which can
 	unconditionally be rebuilt.  Prevent signalent.h from being
 	unconditionally being rebuilt since it's customized.
	* {sunos4,linux{,/alpha},svr4}/{ioctlent,errnoent,signalent}.h:
 	Use versions built by {ioctlent,errnoent,signaltent}.sh.
  	* sunos4/ioctlent.sh: Work around sprintf troubles with SunOS
 	4.1.4 and gcc 2.7.2.

Sun May 19 17:14:09 1996  J. Richard Sladkey  <[e-mail]>

	* configure.in, Makefile.in: Add OSARCH concept to finish
	build support for the alpha.
	* Makefile.in, linux/Makefile.in: Rewrite clean, distclean,
	and maintainer-clean rules.
	* defs.h, ioctlsort.c: Make ioctl code member unsigned.
	* ioctl.c, ioctlsort.c (compare): Perform explicit checking
	for less, greater, and equal since subtraction on two's
	complement numbers isn't an order relation (it isn't transitive)!
	* linux/Makefile.in: Add rules for the signalent.h file.
	* linux/alpha/Makefile.in: New file.

Sun May 19 01:12:28 1996  J. Richard Sladkey  <[e-mail]>

	* syscall.c (set_personality): New.
	* strace.c (main): Call set_personality.
 	* defs.h, syscall.c, ioctl.c, signal.c: Make sysent, errnoent,
 	ioctlent, and signalent indirect pointers and redirect them
	based on personality.
	* {sunos4,svr4,linux{,/alpha}}/signalent.h: New files.
	Suggested by Tom Dyas <[e-mail]>.

	* util.c (upeek): Handle case where ptrace returns a long
	and sizeof(long) != sizeof(int).
	From Richard Henderson <[e-mail]>

	* linux/syscall.h (sys_utimes): Fix a typo in the declaration.
	From Thomas Bogendoerfer <[e-mail]>.

Fri May 17 00:50:06 1996  J. Richard Sladkey  <[e-mail]>

	* version.c: Version 3.0.10 is released.

	* Makfile.in: Add os/arch to includes so that a given arch
	(like alpha) can override the native arch (like i386).
	* configure.in: Check for sendmsg.

	* net.c: Make sendmsg and recvmsg dependent on an autoconf
	test.  Reported by Michael E Chastain <[e-mail]>.

	* acconfig.h, configure.in: Detect the alpha.
	* ioctl.c: Handle the alpha.
	* defs.h: Make some members long for the alpha.  Define
	some register nicknames.  Add support for WAITEXECVE.
	* file.c [ALPHA]: Support the alpha for statfs.  Add
	osf_statfs and osf_fstatfs for the alpha.  Make damn sure
	major and minor results are suitable for passing to printf.
	* signal.c, syscall.c: Support the alpha.
	* process.c: Add alpha user offsets.
	* most files: Use %l? for printf arguments since
	most are now longs for the alpha.
	* linux/alpha/{errnoent.h,ioctlent.{h,sh},syscallent.h}:
	New for the alpha.
	From Thomas Bogendoerfer <[e-mail]>.

	* time.c [LINUX]: Explicitly include linux/version.h.

Sat Aug 19 00:06:08 1995  Rick Sladkey  <[e-mail]>
