* 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.
