Wed Sep 16 11:20:31 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libc.h: 
	Remove "fix me" comment which I forgot to remove before

Tue Sep 15 19:27:57 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libc.h: 
	Updated descriptions and a few other minor things after review.
	Notably though, the NDEBUG config option has been removed

1998-09-15  Bart Veer  <[e-mail]>

	* include/pkgconf/libc.h:
	PR 17201: removed dependency on CYGPKG_KERNEL in the option
	CYGNUM_LIBC_MAIN_STACK_SIZE, since the actual dependencies cannot
	be expressed sensibly in the current system.

1998-09-11  Bart Veer  <[e-mail]>

	* include/pkgconf/libc.h:
	Sorting out dependencies for error package.

1998-09-10  Mark Galassi  <[e-mail]>

	* include/pkgconf/libc.h: started adding doc fields to the
	cdl_package data, as a pilot for now.

Wed Sep  9 17:41:23 1998  Hugo Tyson  <[e-mail]>

	* include/pkgconf/libc.h: 
	Add option CYGIMP_LIBC_MALLOC_CXX_DELETE_CALLS_FREE to explicitly
 	control whether the empty delete functions (currently) in
 	kernel/.../common/delete.cxx are enabled; controls code bloat, see
 	the comments in delete.cxx.

Fri Sep  4 16:43:38 1998  Jonathan Larmour  <[e-mail]>

	* tests/stdio/stdiooutput.c: 
	Add a default CYG_TEST_PASS() to make sure the test infra doesn't
	complain.
	Also remove the unused string functionsa

Fri Sep  4 15:43:48 1998  Hugo Tyson  <[e-mail]>

	* src/stdlib/exit.cxx (__libc_exit): 
	* src/stdlib/_exit.cxx (__libc__exit): 
	* src/stdlib/malloc.cxx (_free): 
	* src/stdlib/abort.cxx (abort): 
	* src/support/cstartup.cxx (invoke_main): 
	Tracing system asserted cos it was being called incorrectly; these
	are void functions so you shouldn't give a type to the function
	reporting call.

Fri Sep  4 15:03:10 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libc.h:

	Proven won't be making any changes to the device driver
	implementation after all.
	Fix for PR 17148

	* src/clibincl/stream.inl (set_position): 
	Remove "fix me" line. It is obvious that this will have to change
	with a filesystem interface

	* src/stdio/common/freopen.cxx: 
	Remove "fix me" - I know about this issue
	Fix for PR 17145

	is applicable or not

	* tests/stdlib/rand2.c (test):
	Use CYGNUM_LIBC_RAND_SEED for default seed, not 1

	* tests/string/strtok.c:
	Add extra check for CYGFUN_LIBC_strtok to decide whether the
	test is applicable or not

Wed Sep  2 19:11:40 1998  Jonathan Larmour  <[e-mail]>

	* src/stdio/input/fread.cxx, src/stdio/output/fwrite.cxx:
	Add fread() and fwrite() functions

	* src/PKGconf.mak:
	Build fread.cxx and fwrite.cxx from above

Tue Sep  1 19:44:58 1998  Jonathan Larmour  <[e-mail]>

	* src/i18n/locale.cxx:
	Fix bug in find_locale_data() that miscalculated size of
	all_locales
	
	Make find_locale_data() match the locale "" and add some

	* tests/PKGconf.mak:
	Update to build setlocale.c test

	* src/support/cstartup.cxx:

	* src/i18n/locale.cxx (_setlocale): 
	Fix tracing macro name and remove "str maybe used before
	initialised" warning

	* tests/stdlib/qsort.c: 
	Correct file description header

Tue Sep  1 17:04:32 1998  Jonathan Larmour  <[e-mail]>

	* include/locale.h, src/clibincl/i18nsupp.hxx, src/i18n/locale.cxx:
	New files to add support for locales as defined by the ISO C
	standard. i.e. setlocale() and localeconv() functions and some
	other bits

	* include/pkgconf/libc.h:
	Add CYGNUM_LIBC_MAX_LOCALE_NAME_SIZE config option for locale
	support

	* src/PKGconf.mak:
	build locale.cxx
	
	* include/errno.h, src/clibincl/ctypesupp.hxx: 
	Tidy up to 76 columns

Tue Sep  1 00:24:22 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libc.h:
	Move environment-related options from stdlib into new
	CYGPKG_LIBC_STARTUP component. Also add options for main()'s
	arguments (CYGPKG_LIBC_ARGUMENTS), main()'s default stack size
	(CYGNUM_LIBC_MAIN_STACK_SIZE), number of atexit handlers
	(CYGNUM_LIBC_ATEXIT_HANDLERS), and whether _exit() stops the
	system (CYGSEM_LIBC_EXIT_STOPS_SYSTEM).

	* src/clibincl/stdlibsupp.hxx:
	Fix a few comment bugs, and add new
	cyg_libc_invoke_atexit_handlers() function prototype

	* src/stdlib/_exit.cxx, src/stdlib/atexit.cxx, src/stdlib/exit.cxx:
	Implement exit(), atexit() and _exit() correctly now. Also
	includes cyg_libc_invoke_atexit_handlers() in atexit.cxx. Now
	we get the correct behaviour of atexit(), and exit() invokes the
	atexit handlers and fflushs all the stdio streams. Add plenty of
	tracing of asserts too.

	* src/support/cstartup.cxx: 
	Make main_thread object an exported global. Allow user-settable
	arguments. Add MUCH more tracing and asserts. Improve comments.
	Tidy up to 76 columns

	* tests/stdlib/atexit.c:
	Add simple test for atexit() and it calling registered functions

	* tests/PKGconf.mak:
	Build atexit.c test

	* src/stdlib/getenv.cxx, tests/stdlib/getenv.c:
	Add support for getenv(), and some tests to ensure it works

	* src/PKGconf.mak, tests/PKGconf.mak:
	Update to include getenv.cxx and getenv.c test

	* src/clibincl/clibdata.hxx:
	remove prototype for environ - we expect files needing it to
	define it themselves

	* src/support/clibdata.cxx:
	Tidy up to 76 columns and add definition of char **environ, but
	with a configurable initialiser (see libc.h below)

	* tests/stdlib/abs.c (main): 
	Tidy up to 76 columns

	* src/stdlib/malloc.cxx: 
	Tidy up to 76 columns and remove warning for undefined _memcpy()
	by changing to memcpy(), and casting away signedness

	* include/pkgconf/libc.h:
	Add CYGPKG_LIBC_ENVIRONMENT and CYGDAT_LIBC_DEFAULT_ENVIRONMENT
	configuration options

	* include/pkgconf/libc.h, src/clibincl/clibdata.hxx: 
	Tidy up to 76 columns

	* include/stdlib.h: 
	Add getenv() prototype and tidy up to 76 columns

	* src/clibincl/stdlibsupp.hxx: 
	Add _getenv() prototype
	
Mon Aug 31 13:37:08 1998  Jonathan Larmour  <[e-mail]>

	* src/stdlib/malloc.cxx:
	Add realloc()

	* tests/stdlib/realloc.c:
	Add this file to test new realloc() functionality

	* tests/PKGconf.mak:
	Build realloc test

	* tests/stdlib/malloc3.c (main), tests/stdlib/malloc2.c (main),
	  tests/stdlib/malloc1.c (main): 
	Conditionalise local vars to prevent warnings

	* tests/stdlib/malloc3.c (fill_with_data): 
	Move '{' into "verb" line

	* include/pkgconf/libc.h: 
	Require infra tracing support to allow tracing

	* include/stdlib.h:
	Add realloc()

	* src/clibincl/stdlibsupp.hxx: 
	Update the commented argument names from stdlib.h, including realloc()

1998-08-28  Bart Veer  <[e-mail]>

	* include/pkgconf/libc.h:
	* src/clibincl/clibdata.hxx, src/time/clock.cxx:
	
	Updated for new kernel configuration option symbol names

Fri Aug 28 19:18:25 1998  Hugo Tyson  <[e-mail]>

	Changed the entry below to sat "tx39" instead of "mn10300".
	It's been a long week.

Fri Aug 28 18:59:20 1998  Hugo Tyson  <[e-mail]>

	* src/support/cstartup.cxx: Add a weakly named main to allow the
 	default configuration to link on the tx39 which has no
 	scalextric linking yet.  The static Cyg_Thread main_thread object
 	below continues to exist, though unreferenced, so all its
 	descendants must exist too.

Fri Aug 28 08:54:29 1998  Jonathan Larmour  <[e-mail]>

	* include/stdlib.h: 
	Add commented argument names Add exit(), and atexit(). And move
 	these along with abort() and _exit() to a new section.

	* src/stdlib/atexit.cxx, src/stdlib/exit.cxx:
	Add trivial versions of atexit() and exit()

	* include/pkgconf/libc.h:
	Add CYGNUM_LIBC_MAIN_STACK_SIZE config option

	* include/sys/cstartup.h, src/support/cstartup.cxx, src/PKGconf.mak:
	New files to provide a new function cyg_iso_c_support(), which
	invokes main "correctly".

	Modify all tests to use new startup mechanism, and cyg_iso_c_start()

Fri Aug 28 00:29:38 1998  Jonathan Larmour  <[e-mail]>

	* src/stdio/common/stream.cxx: 
	Add #ifdef CYGSEM_LIBC_STDIO_WANT_BUFFERED_IO around all accesses to
	flags.last_buffer_op_was_read. Fix for PR 16997
