poll: fixes for large fds
* lib/poll.c (poll): Don't check directly for NFD too large.
Don't rely on undefined behavior in FD_SET when an arg exceeds
FD_SETSIZE. Always set revents afterwards, even if to zero.
* tests/test-poll.c (poll1): Set revents to -1 instead of 0,
as that makes the test a bit stricter.

$Id: COPYING,v 1.3 2006-10-26 16:20:28 eggert Exp $ The files in here are mostly copyright (C) Free Software Foundation, and are under assorted licenses. Mostly, but not entirely, GPL. Many modules are provided dual-license, either GPL or LGPL at your option. The headers of files in the lib directory (e.g., lib/error.c) state GPL for convenience, since the bulk of current gnulib users are GPL'd programs. But the files in the modules directory (e.g., modules/error) state the true license of each file, and when you use 'gnulib-tool --lgpl --import <modules>', gnulib-tool either rewrites the files to have an LGPL header as part of copying them from gnulib to your project directory, or fails because the modules you requested were not licensed under LGPL. Some of the source files in lib/ have different licenses. Also, the copy of maintain.texi in doc/ has a verbatim-copying license, and doc/standards.texi and make-stds.texi are GFDL.
