* config/mt-linux: Define CXXFLAGS to make sure -fvtable-thunks is
used.
* configure.in: Name Linux target fragment.
* configure: Rewrite so that project Makefile fragment is inserted
first and appears last in the resulting Makefile.
Thu Sep 11 16:40:46 1997 H.J. Lu (hjl@gnu.ai.mit.edu)
* Makefile.in (local-distclean): Also remove mh-frag mt-frag.

libio/ChangeLog
1997-09-15 02:37 Ulrich Drepper <drepper@cygnus.com>
* config/linux.mt: Rewrite for use with glibc 2.
* config/linuxlibc1.mt: Old content of linux.mt, fir libc4 and
libc5.
* config.shared (COMPILE.c): Allow new flags in MT_CFLAGS be
passed.
(COMPILE.cc): Likewise.
* configure.in (*-linux*): Remove goal. We now have...
(*-linux-gnulibc1): For libc4 and libc5. Emit warning.
(*-linux-gnu)): For glibc 2.
Create links to find headers for multi-threading if necessary.
* fileops.c: Make thread-safe by using _IO_cleanup_region_start
etc to handle cancelation. Acquire locks in functions which are
called directly.
(_IO_file_read, _IO_file_write): Remove dead code.
* include/empty.h: Define stub macros for locking.
* iolibio.h: Add prototypes for obstack printing functions.
* ioseekoff.c (_IO_seekoff): Lock stream before working.
* ioseekpos.c (_IO_seekpos): Likewise.
* iostream.cc: Add support for long double I/O.
Use __printf_fp from glibc is available.
Use _IO_cleanup_region_start to handle cancelation correctly.
* iostream.h (class ostream): Change opfx and osfx to lock/unlock
stream
(class istream): Likewise for ipfx, ipfx0, ipfx1, and isfx.
Declare new function lock and unlock for ostream and istream.
* osform.cc: Use _IO_cleanup_region_start to handle cancelation
correctly.
* libio.h: Update from glibc version. Pretty printing.
* libioP.h: Likewise.
* outfloat.c: Only compile if _IO_USE_DTOA is defined.
* stdio/feof.c: Make thread safe.
* stdio/ferror.c: Likewise.
* stdio/getc.c : Likewise.
* stdio/putc.c : Likewise.
* stdio/stdio.h: Declare function of thread-safe API.
* stdio/obprintf.c: New file.
* stdio/vasprintf.c: New file.
* stdio-lock.h: Removed.
* stdstrbufs.c: Add definitions for thread-safe streams.
* streambuf.cc: Initialize lock.
* strops.c (_IO_str_count): Undo last change.
* tests/tFile.cc: Support parallel builds by avoiding fixed
name for test file.
Thu Sep 11 18:43:56 1997 Jason Merrill <jason@yorick.cygnus.com>
* Makefile.in (iostream.list): Remove STDIO_WRAP_OBJECTS.
