	QA improvements

1999-02-04  Jesper Skov  <[e-mail]>

	* src/support/cstartup.cxx: Only define cyg_libc_main_thread when
	the kernel is around.

1999-02-01  Jesper Skov  <[e-mail]>

	* tests/time/clock.c: Joined the two test/NOP checks into
	one. 
	Increased tolerance in attempt to fix PRs 18737,18787,18846.
	Fixed typo.

1999-01-28  Jonathan Larmour  <[e-mail]>

	* src/string/strtok.cxx: 
	* src/stdlib/rand.cxx: 
	Include <pkgconf/kernel.h> if we use kernel header files

1999-01-25  Jonathan Larmour  <[e-mail]>

	* tests/stdio/sscanf.c (test): 
	CYGSEM_LIBC_STDIO_PRINTF_FLOATING_POINT should be
	CYGSEM_LIBC_STDIO_SCANF_FLOATING_POINT
	Fix for PR 18786

	* src/string/strtok.cxx: 
	* src/stdio/common/stdiofiles.cxx:
	* src/errno/errno.cxx: 
	* src/stdlib/rand.cxx: 
	Give mutex protection objects a libc constructor priority

	* src/support/invokemain.cxx:
	Add prototype for cyg_hal_invoke_constructors()

	* src/support/mainthread.cxx:
	Give cyg_libc_dummy_constructor_obj a libc constructor priority,
	and make its class have a public constructor

	* src/stdio/common/stderr.cxx: 
	* src/stdio/common/stdout.cxx: 
	* src/stdio/common/stdin.cxx: 
	Give cyg_libc_stdio_stdin/out/err static objects a libc constructor
	priority
	
	* src/clibincl/streambuf.hxx (class Cyg_StdioStreamBuffer): 
	* src/clibincl/stream.hxx (class Cyg_StdioStream): 
	Remove private copy constructor. Needed to make prioritised
	static constructors work. Fix for PR 18898

1999-01-22  Jonathan Larmour  <[e-mail]>

	* src/errno/errno.cxx: 
	Include pkgconf/kernel.h otherwise it fails with per-thread errno
	enabled

	* include/pkgconf/libc.h: 
	Enable per-thread errno by default since that is what POSIX would
	want

	* tests/time/clock.c (test): 
	Placate compiler by initializing clock_first/second/third anyway,
	even though they won't be in practice. This is only a test program
	so adding an extra instruction doesn't matter.

	* src/i18n/locale.cxx (_setlocale): 
	Placate compiler, since it is dumb, by nesting, not serializing, if's
	This is an idempotent change, but screws up the formatting :-(.

	* src/string/strpbrk.cxx (_strpbrk): 
	Change while loop to do loop to placate compiler. It'll even save an
	instruction too (wow!)
	
1999-01-22  John Dallaway  <[e-mail]>

	* tests/stdlib/realloc.c: 
	* tests/stdlib/malloc3.c:

	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]>

	are not used.

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

	shouldn't have.

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

	* src/stdlib/qsort.cxx (_qsort):

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

	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

	* 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
