Update.
1998-04-30 16:45 Ulrich Drepper <drepper@cygnus.com> * inet/ether_aton.c: Including netinet/if_ether.h is not necessary. * locale/Makefile (distribute): Add programs/repertoire.h. (localedef-modules): Add repertoire. (CPPFLAGS): Define REPERTOIREMAP_PATH. * locale/programs/repertoire.c: New file. * locale/programs/repertoire.h: New file. * locale/programs/charmap.c: Starting fixing character set handling to handle multi-byte encodings. * locale/programs/charset.c: Likewise. * locale/programs/charset.h: Likewise. * locale/programs/ld-collate.c: Likewise. * locale/programs/ld-ctype.c: Likewise. * locale/programs/linereader.c: Likewise. * locale/programs/localedef.c: Likewise. * locale/programs/locfile-kw.gperf: Likewise. * locale/programs/locfile-kw.h: Likewise. * locale/programs/locfile-token.h: Likewise. * locale/programs/locfile.h: Likewise. * locale/programs/stringtrans.c: Likewise. 1998-04-18 Philip Blundell <Philip.Blundell@pobox.com> * sysdeps/arm/memset.S: Fix off by one error. * sysdeps/unix/sysv/linux/arm/sysdep.h (PSEUDO): On error, call __syscall_error rather than syscall_error directly. 1998-04-17 Philip Blundell <Philip.Blundell@pobox.com> * sysdeps/unix/sysv/linux/arm/mmap.S: New file; implementation of mmap() syscall for ARM. * sysdeps/unix/arm/start.c: New file; startup code for ARM a.out binaries.
