1999-01-15  Gary Thomas  <[e-mail]>

	* include/pkgconf/libc.h (CYGNUM_LIBC_MAIN_STACK_SIZE): 
	(CYGNUM_LIBC_MALLOC_MEMPOOL_SIZE): Change defaults to be
	more reasonable on small systems.

1999-01-04  Jonathan Larmour  <[e-mail]>

	* src/support/clibdata.cxx: 
	Minor bug with environ not being initialised correctly by
	default

1998-12-24  Bart Veer  <[e-mail]>

	* src/clibincl/stream.inl (Cyg_StdioStream):
	check_this() member functions should now be const

1998-12-22  Jonathan Larmour  <[e-mail]>

	* src/string/memchr.cxx (_memchr): 
	treat search value parameter to memchr as an unsigned byte,
	not a signed int - copied fix from newlib PR 18471

1998-12-21  Jonathan Larmour  <[e-mail]>

	* tests/stdlib/realloc.c: 
	* tests/stdlib/malloc3.c: 
	* tests/stdlib/malloc2.c: 
	Warning cleanup

1998-12-14  Jonathan Larmour  <[e-mail]>

	* tests/stdlib/malloc2.c, tests/stdlib/malloc3.c,
	  tests/stdlib/realloc.c: 
	Only run these tests when we have a coalescing memory allocator

1998-12-14  Jonathan Larmour  <[e-mail]>

	* src/stdio/common/stream.cxx:
	Only check buffer init success if buffering

	* src/stdio/common/streambuf.cxx (set_buffer): 
	Check for diff of requested size against buffer_size, not
	get_buffer_size(), since this may return -1, which won't be
	equal to size, and will cause malloc to be called

1998-12-01  Jesper Skov  <[e-mail]>

	* tests/stdlib/getenv.c (main): Don't declare variables when they
	are not used.

Thu Nov 26 17:59:12 1998  Jonathan Larmour  <[e-mail]>

	* tests/string/strncpy1.c: 
	Fix off-by-one error since it called my_strcmp() and not
	my_strncmp(), which meant in included the trailing NULL when it
	shouldn't have.

1998-11-26  Jesper Skov  <[e-mail]>

	* src/stdlib/qsort.cxx (_qsort): 
	* src/stdlib/rand.cxx (_srand): 
	Changed CYG_REPORT_FUNCNAMETYPE to CYG_REPORT_FUNCNAME in void
	functions.

Mon Oct 26 18:49:00 1998  Jonathan Larmour  <[e-mail]>

	Silence compiler warning with cast of char * to CYG_ADDRWORD

Wed Oct 28 17:31:21 1998  Jonathan Larmour  <[e-mail]>

	* src/time/clock.cxx (_clock): 
	Reorder scaling expression as it was both incorrect and risked
	overflow.
	Fix for PR 18076

Mon Oct 19 14:40:06 1998  Jonathan Larmour  <[e-mail]>

	* include/stdio.h (EOF): 
	Change from -64 to (-1), to allow broken code to work :-/
	Also change other negative defines to be within parentheses

1998-10-19  Mark Galassi  <[e-mail]>

	* include/pkgconf/libc.h: updated the doc URL

Thu Oct 15 21:33:44 1998  Jonathan Larmour  <[e-mail]>

	* src/clibincl/clibdata.hxx:
	Only include kernel thread headers when we're in thread-safe mode

	* src/time/clock.cxx:
	Only include kernel clock headers if there's a kernel with the
	right functionality available

	* tests/time/clock.c:
	Remove unnecessary inclusion of <pkgconf/kernel.h>

	Above changes are required for PR 17229

Wed Oct 14 16:38:55 1998  Jonathan Larmour  <[e-mail]>

	* src/clibincl/clibdata.hxx, src/clibincl/clibdata.inl: 
	Conditionalise inclusion of clibincl/stdiosupp.hxx and
	clibincl/stream.hxx. Tidying up PR 17502

Wed Oct 14 14:08:56 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libc.h:
	Rename CYGPKG_LIBC_STRING_OPTIMISATIONS to
	CYGPKG_LIBC_STRING_OPTIMIZATIONS to make it truely merkin.

Tue Oct 13 19:34:41 1998  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libc.h (CYGDAT_LIBC_ARGUMENTS): 
	Add a default argv[0] of "" as many programs assume argc>0
	The standard allows argv[0] to be "" if the program name
	is not available

1998-09-26  Bart Veer  <[e-mail]>

	* src/clibincl/stdiosupp.hxx: 
	PR 17502: this header file now does nothing if the stdio option
	is disabled completely. This is the same behaviour is
	clibincl/stream.hxx, although arguably the #ifdef protection
	should happen wherever the header file is #include'd rather than
	in the header file itself.
	
	* src/clibincl/clibdata.hxx:
	PR 17502: this header file still #include's internal stdio-related
	header files and references the FILE structure, even if stdio is
	disabled. There were some #ifdef's for CYGPKG_LIBC_STDIO already.
	One more has been added for _fopen() and _fclose().

1998-09-25  Bart Veer  <[e-mail]>

	* src/clibincl/streambuf.inl (Cyg_StdioStreamBuffer):
	PR 17487: Reorder the calls to initialize member fields, to
	eliminate a compiler warning.

Fri Sep 25 19:04:29 1998  Jonathan Larmour  <[e-mail]>

	* src/errno/errno.cxx, src/stdlib/bsearch.cxx,
	  src/stdlib/qsort.cxx, src/stdlib/rand.cxx, src/string/strtok.cxx,
	  src/time/clock.cxx:
	Only define tracing variable and tracing level macro when
	the relevant tracing level config options are set. Otherwise
	keep the tracing level fixed at 0
	Fix for PR 17476

	* include/pkgconf/libc.h: 
	Define trace levels only if parent CYGPKG_LIBC_TRACE is defined
	for consistency with Configuration Tool
	

Fri Sep 25 17:24:45 1998  Jonathan Larmour  <[e-mail]>

	* src/stdio/common/stdioinlines.cxx: 
	Make definition of vscanf() dependent on CYGFUN_LIBC_STDIO_ungetc
	otherwise _vfscanf() won't be compiled. This therefore would
	cause a link fail iff selective linking is not enabled.
	Fix for PR 17455

Fri Sep 25 17:23:17 1998  Jonathan Larmour  <[e-mail]>

	* src/stdlib/rand.cxx: 
	Make compilation dependent on CYGPKG_LIBC_RAND
	Fix for PR 17473

	* tests/stdlib/srand.c: 
	Make definition of dummy test pass conditional on CYGPKG_LIBC_RAND
	not being defined, as well as CYGPKG_LIBC
	Caused compilation failure when testing PR 17473 fix

Mon Sep 21 17:11:04 1998  Jonathan Larmour  <[e-mail]>

	* tests/stdio/sscanf.c: 
	Make sscanf test conditional on CYGFUN_LIBC_STDIO_ungetc since
	_vfscanf() only gets compiled if this is defined
	Fix for PR 17346

1998-09-20  Mark Galassi  <[e-mail]>

	* include/pkgconf/libc.h: updated CDL doc strings.

Fri Sep 18 22:18:47 1998  Jonathan Larmour  <[e-mail]>

	* src/clibincl/clibdata.inl (get_errno_p): 
	Rather than this function only being available in thread-safe mode,
	instead make what it returns be either the per-thread errno, or
	global errno depending on the configuration.
	Include <errno.h> (conditionally) to support this change

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
	Fix for PR 17147
	
	* src/stdio/common/freopen.cxx: 
	Remove "fix me" - I know about this issue
	Fix for PR 17145

	is applicable or not

	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
