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).
