Subject: [PATCH] Fix cproj handling of (finite, NaN) arguments (bug 15531).

commit c980f2f4fe0f5d301f706017a1f7e4e942193ec0
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Tue Aug 20 19:41:15 2013 +0000

    Fix cproj handling of (finite, NaN) arguments (bug 15531).

	* math/s_cprojf.c (__cprojf): Only return an infinity if one part of
	argument is infinite.

This patch is added so as to compile isnan multiarch implementation
successfully since __GI___isnanf is missing.This wll be fixed later in master.
