1997-10-15 06:56 Ulrich Drepper <drepper@cygnus.com> * Rules: Remove ruls to magically install <subdir>.h headers. Reported by Mark Kettenis <kettenis@phys.uva.nl>. * glibcbug.in: Fix @gnu.ai.mit.edu -> @gnu.org. * version.c: Likewise. * catgets/gencat.c: Likewise. * db2/makedb.c: Likewise. * locale/programs/locale.c: Likewise. * locale/programs/localedef.c: Likewise. * libc.map: Move _IO_list_all back to GLIBC_2.0. * elf/rtld.c: Provide name of running program to _dl_new_object. * Rules: Implement shared-only-sources. * include/libc-symbols.h: Define default_symbol_version. * libio/Makefile (shared-only-sources): Define. * libio/freopen.c: Define as default version. * libio/iofopen.c: Likewise. * libio/genops.c: Define _IO_list_all here. * libio/stdfiles.c: Create linked list with public names. * libio/oldstdfiles.c: Likewise. * stdio-common/printf.c: Optimize. * stdio-common/scanf.c: Optimize. * sysdeps/generic/setfpucw.c: Include #include <...> not "...". * sysdeps/i386/i486/bits/string.h: Add optimized versions of index and rindex. 1997-10-14 Andreas Jaeger <aj@arthur.rhein-neckar.de> * manual/arith.texi: Spelling fixes. * manual/conf.texi: Likewise. * manual/creature.texi: Likewise. * manual/filesys.texi: Likewise. * manual/intro.texi: Likewise. * manual/llio.texi: Likewise. * manual/math.texi: Likewise. * manual/message.texi: Likewise. * manual/pattern.texi: Likewise. * manual/search.texi: Likewise. * manual/signal.texi: Likewise. * manual/socket.texi: Likewise. * manual/startup.texi: Likewise. * manual/stdio.texi: Likewise. * manual/string.texi: Likewise. * manual/time.texi: Likewise. * manual/users.texi: Likewise. 1997-10-13 05:25 Ulrich Drepper <drepper@cygnus.com> * sysdeps/generic/sys/mman.h: Use __ptr_t instead of __caddr_t. * sysdeps/unix/bsd/osf/sys/mman.h: Likewise. * sysdeps/unix/bsd/sun/sunos4/sys/mman.h: Likewise. * sysdeps/unix/bsd/ultrix4/sys/mman.h: Likewise. * sysdeps/unix/sysv/irix4/sys/mman.h: Likewise. * sysdeps/unix/sysv/linux/sys/mman.h: Likewise. * sysdeps/mach/hurd/mmap.c: Likewise. * sysdeps/generic/mmap.c: Likewise. * sysdeps/unix/bsd/sun/sunos4/mmap.c: Likewise. * sysdeps/mach/munmap.c: Likewise. * sysdeps/generic/munmap.c: Likewise. * sysdeps/mach/mprotect.c: Likewise. * sysdeps/generic/mprotect.c: Likewise. * sysdeps/generic/msync.c: Likewise. * sysdeps/generic/madvise.c: Likewise. * sysdeps/unix/sysv/linux/madvise.c: Include stub version from generic subdir. 1997-10-12 20:27 Zack Weinberg <zack@rabi.phys.columbia.edu> * sysdeps/stub (all files): Moved to sysdeps/generic. * all files using stub_warning: Include <stub-tag.h>. * include/stub-tag.h: New file, marks stubs in .d files. * Makerules: Look for stub-tag.h, not sysdeps/stub, when building <gnu/stubs.h>. * configure.in: Don't add sysdeps/stub to $sysnames. * sysdeps/unix/Makefile: Look for generic headers, not stub headers. * sysdeps/generic/Makefile: Likewise. * manual/maint.texi: Delete references to sysdeps/stub. * INSTALL: Rebuilt. * configure: Rebuilt.
