2011-01-09 Ulrich Drepper <drepper@gmail.com>
* sysdeps/i386/bits/select.h: Don't use asm code for __FD_SET,
__FD_CLR, and __FS_ISSET. gcc generates better code on its own.
* sysdeps/x86_64/bits/select.h: Mark value of __FD_SET and __FD_CLR as
void.
* bits/select.h: Likewise.
2011-01-08 Ulrich Drepper <drepper@gmail.com>
* po/ja.po: Update from translation team.
