Subject: Fix sigpause namespace (bug 21554).
X-Git-Tag: upstream/2.30~3321
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b85995291e8db20bb08a64f409268ce7ffb7ed93;p=platform%2Fupstream%2Fglibc.git

Fix sigpause namespace (bug 21554).

The sigpause function is declared for __USE_XOPEN.  As it's new in
XPG4.2 it should be declared only for __USE_XOPEN_EXTENDED.  This
patch fixes the declaration accordingly.

Tested for x86_64.

	[BZ #21554]
	* signal/signal.h (sigpause):: Declare if [__USE_XOPEN_EXTENDED],
	not [__USE_XOPEN].
