Thu Dec 12 03:32:21 1996  Ulrich Drepper  <drepper@cygnus.com>

	* libio/_G_config.h: Add definition of _G_int16_t, _G_int32_t,
	_G_uint16_t, _G_uin32_t, _G_HAVE_BOOL, _G_HAVE_MMAP, and
	_G_ARGS.

	Change libio buffer handling to allocate internal buffers using
	mmap if possible.
	* libio/filedoalloc.c (_IO_file_doallocate): Change call to
	ALLOC_BUF.
	* libio/genops.c (_IO_setb, _IO_default_finish): Change call
	to FREE_BUF.
	(_IO_default_doallocate): Change call to ALLOC_BUF.
	* libio/libioP.h: Change definition of ALLOC_BUF and FREE_BUF
	to use mmap/munmap when possible.
	* libio/memstream.c: Don't use ALLOC_BUF, but directly malloc.
	* libio/vasprintf.c: Likewise.
	Patch by HJ Lu.

	* libio/libio.h: Define NULL as __null only for gcc-2.8 and up.
	* libio/libioP.h: Likewise.

	* libio/fileops.c (_IO_file_read, _IO_file_write): Don't
	restart syscall when EINTR was returned.  Necessary for POSIX.1.

	* libio/strops.c (_IO_str_overflow): Add cast to prevent warning.

	* new-malloc/malloc.c (heap_trim): Correctly place parentheses to
	prevent warnings.

	* nis/nss_nis/nis-service.c: Likewise.
	* nis/nss_nis/nis-spwd.c: Likewise.

	* nis/rpcsvc/yp_prot.h (ypreq_key): Change type of members to
	`const char *'.
	(ypmaplist): Change member names to `map' and `next' and provide
	#defines for old names.
	Patch by Thorsten Kukuk.

	* nss/nss_files/files-parse.c (parse_line, parse_list): Change
	type for `datalen' parameter to size_t.

	* shsdow/lckpwdf.c: Use fcntl forlocking, not flock.

	* stdio-common/printf.c [USE_IN_LIBIO]: Provide alias _IO_printf
	for printf.
	* stdio-common/sscanf.c [USE_IN_LIBIO]: Provide alias _IO_sscanf
	for sscanf.
	Patch by HJ Lu.

	* stdio-common/tmpfile.c: Update copyright.

	signal SIGABRT.

	* sysdeps/i386/fpu/__math.h: Define __NO_MATH_INLINES if not using
	gcc-2.8 or up.
	Patch by HJ Lu.

	* sysdeps/posix/tempname.c: Test for error but EEXIST after open
	call.  If EMFILE, ENFILE, or EINTR return with error.

Wed Dec 11 14:43:52 1996  Ulrich Drepper  <drepper@cygnus.com>

	* gnu-versions.h: Set _GNU_OBSTACK_INTERFACE_VERSION back to 1.
	We are compatible again.
	* new-malloc/obstack.h (struct obstack): Add back alloc_failed bit
	even though it is not used.
	* malloc/obstack.h: Likewise.
	* new-malloc/obstack.c (_obstack_begin, _obstack_begin_1): Initialize
	alloc_failed bit to 0.

	* time/strftime.c: Extend for Emacs' needs.  Recognize field width,
	%P format and `0' modifier.

	* Makerules (make-link): Don't discard exit codes of intermediate
	commands.  Always use rellns-sh if symbolic links are available.

Tue Dec 10 20:09:51 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/netinet/in.h: Enclose #include
	<linux/in.h> in __BEGIN_DECLS/__END_DECLS to avoid linkage
	conflict of ntohs etc. in <asm/byteorder.h>.
