	_G_uint16_t, _G_uin32_t, _G_HAVE_BOOL, _G_HAVE_MMAP, and

	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

	Patch by HJ Lu.

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

	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

	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

	* sysdeps/unix/sysv/linux/netinet/in.h: Enclose #include
