[Bug libc/11093] New: <poll.h> does not define POLL[RD|WR]* macros with _POSIX_C_SOURCE="200809L"

["andrey dot vihrov at gmail dot com" <sourceware-bugzilla at sourceware dot org>]

As of POSIX.1-2008, the <poll.h> header was moved completely to the base
specification [1]. Therefore, a definition of _POSIX_C_SOURCE to 200809L alone
should be enough to get all definitions in <poll.h> specified by POSIX.1-2008.
Currently, however, the POLLRDNORM, POLLRDBAND, POLLWRNORM and POLLWRBAND depend
on _XOPEN_SOURCE.

Test program:

#define _POSIX_C_SOURCE 200809L

#include <poll.h>

int main (void)
{
	struct pollfd fds[] = {
		{
			.fd     = 0,
			.events = POLLIN | POLLRDNORM | POLLRDBAND
		},
		{
			.fd     = 1,
			.events = POLLOUT | POLLWRNORM | POLLWRBAND
		}
	};

	(void)fds;
}
