Update.
2002-12-20 Art Haas <ahaas@airmail.net>
* sysdeps/gnu/siglist.c: Convert GCC extension initializer
syntax to C99.
2002-12-21 Philip Blundell <philb@gnu.org>
* sysdeps/arm/elf/start.S (_start): Optimise a little. Push stack
top as seventh arg to __libc_start_main.
Reported by paulnash@wildseed.com.
* sysdeps/unix/sysv/linux/arm/clone.S: Small optimisation.
* sysdeps/unix/sysv/linux/arm/sigcontextinfo.h: Elide
compatibility cruft when new enough kernel is assumed.
