1998-10-13 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/sparc/sparc32/sigaction.c: Include string.h to get memcpy prototype and NULL definition. 1998-10-12 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * misc/sys/cdefs.h (__THROW): New macro. * argp/argp.h: Use it to replace the kludgey __P in inline function definitions. * sysdeps/unix/sysv/linux/bits/socket.h: Likewise. * stdlib/stdlib.h: Likewise. * wcsmbs/wchar.h: Likewise. * libio/stdio.h: Likewise. * stdio/stdio.h: Likewise. * sysdeps/wordsize-64/inttypes.h: Likewise. * sysdeps/wordsize-32/inttypes.h: Likewise. * string/argz.h: Likewise. * io/sys/stat.h: Likewise. 1998-10-12 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * Rules (stdio_lim): New variable. ($(stdio_lim:h=st)): Use this as intermediate stamp file, depend on Rules and config.make, use $(move-if-change) to avoid unnessary recompilations, and cleanup command. (common-generated): Add bits/stdio_lim.st.
