That doesn't sound right.  It see flex being run every time I create a

Sounds like a bug. I did a quick check with a contrib/gcc_update -- touch and a c,treelang build and sure enough, flex is run 5 times, so, unless this bug is fixed, everyone that has an older flex will get build errors. :-( I think this bug should be fixed before we update the minimum version requirements for flex. If it was, I'd support updating the min version required.
