+Subject: [PATCH] Fix glibc feature macro handling for timegm
+
+The way strptime is activated using feature macros, _DEFAULT_SOURCE
+(successor to _BSD_SOURCE) is disabled implicitly, so timegm is
+hidden.  Defining _DEFAULT_SOURCE at the same time as the other
+feature macros solves this, and removes the need for the
+TIMEGM_NEEDS_BSD configure macro.
+
+This avoids an implicit declaration of timegm in src/bind.c, and build
+failures with future compilers.
