glibc/stdlib/exit.c
Ulrich Drepper c559a3ca84 Update.
1999-11-25  H.J. Lu  <hjl@gnu.org>

	* stdlib/exit.c (exit): Run funtions only if
	__exit_funcs->idx > 0.

1999-11-25  Ulrich Drepper  <drepper@cygnus.com>

	* manual/charset.texi (iconv Examples): Add iconv call to flush
	state.  Reported by Andrew Clausen <clausen@alphalink.com.au>.

1999-11-25  Andreas Jaeger  <aj@suse.de>

	* manual/install.texi (Running make install): Better describe
	update from libc5.
	Patch by Michael Deutschmann <michael@talamasca.wkpowerlink.com>.

1999-11-25  Andreas Jaeger  <aj@suse.de>

	* include/sys/mman.h: Remove K&R compatibility.

1999-11-15  Andreas Jaeger  <aj@suse.de>

	* misc/sys/mman.h: Use __REDIRECT for mmap, correct prototype to
	use __off64_t.

1999-11-25  Ulrich Drepper  <drepper@cygnus.com>

	* iconv/iconv_prog.c (process_block): For stateful charsets write
	out byte sequence to get to initial state at the end of the file.

	which was reported to not work (which proofed to be wrong).
