Sun Jan 26 05:41:42 1997  Ulrich Drepper  <drepper@cygnus.com>

	* version.h (VERSION): Bump to 2.0.
	(RELEASE): Now it's "experimental".

	* Makefile (subdirs): Change $(malloc) to malloc.  We have only
	one malloc implementation again.
	* malloc/*: Remove from GNU libc.
	* new-malloc/* Move to malloc/.
	* config.make.in (defines): Remove @USE_NEW_MALLOC@.
	* configure.in: Remove --enable-new-malloc option and check for
	malloc implementation choice.
	* malloc.h: We don't need to check for the implementation to use
	anymore.  Simply include malloc/malloc.h.
	* malloc/Makefile (subdir): Change to malloc.
	* sysdeps/unix/sysv/linux/configure.in: Don't set malloc anymore.

	* Makefile: Add special goal to call generate only-MD5 based crypt
	library.
	* md5-crypt/Makefile: Likewise.

	* stdio-common/tstscanf.c: De-ANSI-declfy.  Update copyright.
	(rounds): Change type to size_t to prevent warning.

	* wcsmbs/btowc.c: Reformat copyright.
