Fri Sep 26 20:56:41 1997 Ulrich Drepper <drepper@rtl.cygnus.com>
Based on a patch by H.J. Lu (hjl@gnu.ai.mit.edu).
* Makefile.in (STDIO_OBJECTS): New. Defined as stdfiles.o.
(LIBIO_OBJECTS): Add $(STDIO_OBJECTS).
(PICFLAG): New, empty. moved to here from config.shared.
* config.shared (DISTCLEAN): Add target-mkfrag.
(PICFLAG): Removed.
* configure.in (*-linux-gnulibc1): Remove warning.
(*-linux-gnu): Use linux.mt mtsafe.mt.
(alpha-*-linux*): Use mh-elfalphapic.
* gen-params (_G_ullong): Also check unsigned long long int.
(_G_llong): Also check long long int.
* libio.h (_IO_lock_t): Add support for the Linux libc 5.
(_IO_peekc): Defined as _IO_peekc_unlocked if _IO_MTSAFE_IO
is not defined.
* iostream.cc (__cvt_double): Fix a typo in declaration.
(info): Use expr != 0 to initialize the bit fields. Don't
initialize "extra" for the Linux libc 5.
* streambuf.h (_G_NEED_STDARG_H): Changed from _IO_NEED_STDARG_H.
* config/linux.mt (STDIO_OBJECTS): New, empty.
(MT_CFLAGS): Removed.
* config/linuxlibc1.mt: Rewrite. it's identical to linux.mt but
IO_OBJECTS mentions files not in early libc5 versions.
* config/mtsafe.mt: New.
* dbz/Makefile.in (check): Support make -j.
* tests/tFile.cc (tempfile): Fix a typo.
Fri Sep 19 11:52:25 1997 Jim Wilson <wilson@cygnus.com>
* Makefile.in (LIBIO_OBJECTS): Depend on _G_CONFIG_H.
