+From: Kurt Roeckx <kurt@roeckx.be>
+Subject: Use %m[ instead of %a[ in scanf()
+
+%a was a gnu extention, but C99 made this a float. So it got
+changed to %m (supported by glibc 2.7), but %a[ and %as are
+still supported by glibc. The portability branch changed this
+from %m to %a again since that's supported by more versions of
+glibc. However gcc gives a warning about this using -Wformat
+and we have a new enough libc to use %m.
