Update.

1998-04-21 21:49  Zack Weinberg  <zack@rabi.phys.columbia.edu>

	* misc/sys/cdefs.h: New macro __REDIRECT to support changing the
	asm symbol name of functions.
	* include/features.h: Kill redundant test.

	* dirent/dirent.h: Use new macros to implement __USE_FILE_OFFSET64.
	* io/ftw.h: Likewise.
	* io/sys/stat.h: Likewise.
	* io/sys/statfs.h: Likewise.
	* io/sys/statvfs.h: Likewise.
	* libio/stdio.h: Likewise.
	* resource/sys/resource.h: Likewise.
	* rt/aio.h: Likewise.

	* posix/unistd.h: Use new macros for __USE_FILE_OFFSET64 and
	 __FAVOR_BSD.
	* signal/signal.h: Use new macros for BSD vs. SysV signal().

	* misc/Makefile: Drop bsd-compat.c.  Make libbsd-compat.a
	a dummy library.
	* misc/bsd-compat.c: Removed.
