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).
