eCos/RedBoot for勤研ARM AnywhereII(4510) 含全部源代码

This ChangeLog file is now obsolete. This is the original ChangeLog from when
libc was one large package, before being separated. It is included for
historical reasons.

	Add missing unlock_me()

	* 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

	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()

	This was exposed by the random combo in PR#19479.

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

	* include/pkgconf/libc.h:

	* tests/ctype/ctype.c:
	Tidy

	* tests/stdlib/rand3.c:
	Fix so that 0..RAND_MAX is split evenly over buckets, which it wasn't
	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

	string, and %y format)
