Upstream is dead, no point submitting a patch to sourceforge just to be
ignored.

+Subject: [PATCH] configure.ac: fix various erroneous bashisms
+
+double equals in shell scripts is ALWAYS wrong. POSIX sh uses single
+equals, and bash implements double equals as an exact alias of the
+single equals form.
+
+Using double equals accomplishes no purpose whatsoever, and for your
+troubles you end up with muscle memory telling you to use it in POSIX sh
+where it fails. Avoid at all costs.
