I've seen reports of problems when people attempted to use flex-2.5.31
with other software packages.  Are you sure that you don't have an old
copy of flex somewhere in your path?  I've used 2.5.4a successfully on
Red Hat 7.3, 8, 9, and Fedora Core 1.

Flex tends to have problems as you describe if the file
/usr/include/FlexLexer.h is from a different release of flex than
the flex binary.

Since the tumble control language is undocumented and unsupported, I
suppose I should conditionalize it so that tumble can be built without
it.
