+https://rt.cpan.org/Public/Bug/Display.html?id=145943
+
+Various fixes for the configure script.  Most of them are specific to
+this package, and not related to autoconf limitations.  The
+configure.in/configure.ac autoconf input is not included among
+upstream sources, so they are not patched here.
