Update.
1998-09-21 10:00 Ulrich Drepper <drepper@cygnus.com> * string/bits/string2.h: Add mempcpy optimization. * sysdeps/generic/mempcpy.c: Undefined __mempcpy. * intl/localealias.c: Define mempcpy only if not already defined. * sysdeps/i386/i486/bits/string.h: Define ffsl only if not already defined. 1998-09-20 10:48 -0400 Zack Weinberg <zack@rabi.phys.columbia.edu> * csu/abi-note.S: Emit the note directly instead of defining a preprocessor macro that's only used once. Don't include sysdep.h. * abi-tags: Generalize Solaris entry. 1998-09-18 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/bsd/getpt.c (__libc_ptyname1, __libc_ptyname2): Change to array to avoid runtime relocation. * sysdeps/unix/sysv/linux/ptsname.c: Update declarations. 1998-09-21 12:22 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * malloc/Makefile ($(objpfx)libmcheck.a): Fix use of $(LN_S). * math/Makefile ($(objpfx)libieee.a): Likewise. 1998-09-21 Ulrich Drepper <drepper@cygnus.com> * sysdeps/generic/getpt.c: Fix order of argument to weak_alias. Patch by John Tobey <jtobey@banta-im.com>.
