+	With latest versions of glibc, a lot of apps failed on a PaX enabled
+	system with:
+		 cannot enable executable stack as shared object requires: Permission denied
+	
+	This is due to PaX 'exec-protecting' the stack, and ld.so then trying
+	to make the stack executable due to some libraries not containing the
+	PT_GNU_STACK section.  Bug #32960.  <azarah@gentoo.org> (12 Nov 2003).
+
+	Patch also NPTL. Bug #116086. <kevquinn@gentoo.org> (20 Dec 2005).
