* sysdeps/unix/sysv/linux/configure.in (LIBC_LINUX_VERSION): New
	macro, now put the needed Linux version just once, here; update to
	needing linux-2.0.3 headers.
	(libc_cv_linuxVER): New macro derived from that.
	(kernel header check): Use those macros and some m4 magic to replace
	hard-coded `201' and `2.0.1' in several places.

	* Makerules ($(libdir)/libc.so): Fix typos in generated comment.

Wed Jul 24 17:02:30 1996  Ulrich Drepper  <drepper@cygnus.com>

	* time/localtime.c: Move lock variable declaration to end of
	variable declarations since if is a dummy macro the ; at the
	end terminates the variable section of the function.

	* time/tzset.c: Undefine `tzset' before function declaration.
	Use `weak_function' macro instead of `weak_symbol'.

Wed Jul 24 18:57:33 1996  Ulrich Drepper  <drepper@cygnus.com>

	* stdlib/strtouq.c: Additional weak alias is `strtoull', not
	`strotull'.

Wed Jul 24 18:26:23 1996  Ulrich Drepper  <drepper@cygnus.com>

	* locale/C-ctype.c: Increment number of fields after change
	from Wed Jun 19 03:24:58 1996.
