Broken build on my system

[Carl Sorensen]

Somehow I've broken the build on my system.  It used to work, but now it
fails when it tries to build the lexer.

I've used git to go back to known-good source trees, e.g.

git checkout 062046e74d6995b99bb7669e4cd6490ba8b18656

which I have built before.

But now, 

make clean
make

exits with the following:

flex -Cfe -p -p -oout/lexer.cc lexer.ll
lexer.ll:595: multiple <<EOF>> rules for start condition longcomment
lexer.ll:621: warning, rule cannot be matched

Any thoughts?

Thanks,
