+Subject: [PATCH 5/5] Add fgetspent_r().
+
+Interface was defined by glibc, and seems to have been adopted by
+Solaris. Some freedesktop software appears to require it, and it adds
+little bloat.
+
+Added without feature test macros, since no other interface in shadow.h
+requires it, even the ones documented to have required it in the past.
