1999-04-19  Jonathan Larmour  <[e-mail]>

	* include/time.inl:
	Ensure all calls to cyg_libc_time_year_is_leap() are with the full
	year, and not the direct contents of a struct tm, which are (year-1900)

1999-04-15  Jonathan Larmour  <[e-mail]>

	* src/clibincl/stdiosupp.hxx:
	Add prototype for new cyg_libc_stdio_flush_all_but() function

	* src/clibincl/stream.hxx:
	Don't include stdiosupp.hxx any more to prevent circular dependency,
	therefore manually provide _setvbuf prototype
	Make sure pkgconf/kernel.h is included before mutex.hxx

	* src/clibincl/stream.inl (Cyg_StdioStream::set_error()):
	Add missing unlock_me()

	* src/stdio/common/fflush.cxx:
	Separate most of code for fflush(NULL) into separate
	cyg_libc_stdio_flush_all_but() function, which has the extra
	capability of omitting one stream

	* src/stdio/common/stderr.cxx:
	* src/stdio/common/stdin.cxx:
	* src/stdio/common/stdout.cxx:
	* src/stdio/common/vsnprintf.cxx:
	* src/stdio/common/vsscanf.cxx:
	Add missing clibincl/stdiosupp.hxx include

	* src/stdio/common/stream.cxx (Cyg_StdioStream::read()):
	When reading, ensure we flush all output streams

	* src/stdio/common/stream.cxx (Cyg_StdioStream::flush_output_unlocked):
	Flush the device as well

1999-04-15  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libc.h:
	* include/stdio.inl (setbuf): 
	Fix dumb typo: BUFSIZE -> BUFSIZ
	This fixes PR19837

1999-04-15  Jonathan Larmour  <[e-mail]>

	* src/stdio/common/stdioinlines.cxx (_setbuf): 
	* include/stdio.inl (setbuf):

	Part of fix for PRs 19731/19607

1999-04-07  Jesper Skov  <[e-mail]>
        PR 19667

	Changed to use the new Cyg_Thread constructor.

1999-04-07  Hugo Tyson  <[e-mail]>

	* tests/signal/signal2.c (main): Use new macro
	HAL_VSR_SET_TO_ECOS_HANDLER if defined, to wrest control from
	CygMon, for example, by reinstalling eCos' default VSRs for
	exceptions that we are provoking.

1999-03-29  Jonathan Larmour  <[e-mail]>

1999-03-29  Jesper Skov  <[e-mail]>

	* tests/signal/signal2.c: Disabled test 3 for PPC as it cannot
	trap division by zero.

1999-03-26  Jonathan Larmour  <[e-mail]>

	* src/support/main.cxx (main): Invoke cyg_user_start() if no kernel
	Only sensible thing to do in our default main in a non-kernel config

1999-03-25  Jonathan Larmour  <[e-mail]>

	* tests/time/time.c: 
	Increase MAX_TIMEOUT since the sparclite gets very close to overrunning
	it even when working.
	Should return -1 iff CYGSEM_LIBC_TIME_TIME_WORKING isn't defined
	Cosmetic changes	

1999-03-25  Hugo Tyson  <[e-mail]>

	* tests/time/time.c (test): Take into account setting of
	CYGSEM_LIBC_TIME_SETTIME_WORKING ie. does cyg_libc_time_settime()
	work?  If not, check that it returns an error.
	This was exposed by the random combo in PR#19479.

1999-03-23  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/libc.h:
	Rename CYGSEM_LIBC_RAND_SIMPLEST and CYGSEM_LIBC_RAND_KNUTH1 to

	before
	Deal with case of RAND_MAX not being divisible by NUM_BUCKETS
	exactly
	Increase TEST_LENGTH to 200000 to provide more representative sample
	Add CYG_TEST_INFO output to help ensure it doesn't time out
	Tidy

	* tests/stdlib/rand4.c:
	Only fail if more than _two_ thirds (rather than one third) match.
	This is because half would match for a perfectly random distribution
	This is the rest of the fix for PR 19562
	Cosmetic changes

1999-03-22  Hugo Tyson  <[e-mail]>

	* src/support/mainthread.cxx (CYGNUM_LIBC_MAIN_STACK_SIZE):

	CYGNUM_HAL_MINIMUM_STACK_SIZE.

1999-03-22  Jonathan Larmour  <[e-mail]>

	* tests/PKGconf.mak: Add -Wno-format when building strftime otherwise

	to fix PR 19562

	* src/stdlib/rand.cxx:
	Add new optional algorithm from Knuth vol.2

	* tests/stdlib/rand4.c:
	Some tidies
	Don't run test when using simplest algorithm

	* tests/signal/signal2.c (main): 
	Don't try to make an FPE on tx39 - its possible to detect but requires
	too much HAL work to be sensible

1999-03-18  Jonathan Larmour  <[e-mail]>

	* src/signal/siginit.cxx (cyg_libc_signals_hwexcept_handler): 
	Use HAL_ENABLE_INTERRUPTS() rather than kernel to enable interrupts

1999-03-18  Mark Galassi  <[e-mail]>

	* tests/PKGconf.mak (TESTS): added rand4 compilation.

1999-03-17  Jonathan Larmour  <[e-mail]>

	* include/time.h: Add #define of __time_t_defined to placate newlib
	if it is used by accident. This is just a temporary workaround though.

1999-03-16  Gary Thomas  <[e-mail]>

	* src/PKGconf.mak: Add compile option to step around ARM compiler bug.

1999-03-16  Jonathan Larmour  <[e-mail]>

1999-03-12  Gary Thomas  <[e-mail]>	

	* include/sys/timeutil.h: 
	* src/time/timeutil.cxx: Remove 'const' from char arrays since
	this fails [silently] on ARM when -fwritable-strings (PR19440)

1999-03-12  Jesper Skov  <[e-mail]>

	* tests/signal/signal2.c (main): Compiler warnings fix was
