eCos操作系统源码

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()

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

	* tests/time/time.c (test): Take into account setting of

	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

	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):

	* include/pkgconf/libc.h (CYGNUM_LIBC_TIME_DST_DEFAULT_STATE): 
	Put brackets back round negative number since sdf says the config
	tool is fixed now (PR 19537)

	options for different rand() algorithms in a so far failed attempt
	to fix PR 19562

	Add new optional algorithm from Knuth vol.2
