I am pleased to report that the recently released flex 2.5.35 generates
code for our .l files that produces no gcc warnings whatsoever.
This is a first :-(, at least for versions of flex without any
downstream patches.

Oh excellent! Now we can build with -Werror without problems (on some
platforms at least, I guess). This should make development and verification
of patches a bit more robust. Just don't pass -Werror to configure or you
will experience very strange behavior. :)
