I think the intent, at least, is to allow people to build Wireshark from
a source release tarball without having Flex (think of a source release
tarball being as much a platform-independent distribution format for
people *not* interested in development, and who are on platforms for
which there aren't binary packages, as a way of getting the source to do
development).  Don't check Flex's capabilities in the configure script
(handling reentrant scanners would have to be done differently).
