update from main archive 961208

Mon Dec  9 03:39:30 1996  Ulrich Drepper  <drepper@cygnus.com>

	* config.make.in (defines): Add @USE_NEW_MALLOC@.
	* Makefile.in: Define USE_NEW_MALLOC to -DUSE_NEW_MALLOC if
	we use the new malloc.

	* malloc.h: Use either <malloc/malloc.h> or <new-malloc/malloc.h>
	depending on USE_NEW_MALLOC.

	Fix some more POSIX.1 problems.
	* libio/fileops.c (_IO_file_underflow): Set errno to EBADF if used
	on a write-only stream.
	(_IO_file_overflow): Set errno to EBADF if used on a read-only
	stream.
	(_IO_file_seekoff): POSIX.1 requires that fseek() after an fflush()
	call really positions the file offset to the correct position
	and no read-ahead happens.

	* locale/C-monetary.c: Set mon_grouping file to "" and "\377"
	to pass POSIX test suite.
	* stdio-common/vfprintf.c: Handle empty string as grouping command
	correctly.
	* stdlib/grouping.h: Likewise.

	* misc/syslog.c: Case first argument of __libc_cleanup_region_start.

	* signal/sigsetops.h: Update copyright.  Don't include ansidecl.h.

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

Sun Dec  8 16:39:28 1996  Andreas Jaeger  <aj@arthur.pfalz.de>

	* time/Makefile: Compile ap.c with NO_MCHECK flag if new-malloc
	used (not otherwise).

	* misc/syslog.c (vsyslog): Cast argument to __libc_cleanup_region
	to get Hurd macros right.
