flex-2.5..31 on Debian definitely broke graphviz builds.

I just tried flex-2.5.33 from  Sourceforge on an x86_64 Rawhide box
and that particular problem seems to be fixed,  but I would have to
test all platform builds to be more confident.


Problems with flex and bison can be particularly obscure and result in
strange breakages in stable code.    Just this week I ran into a problem
in bison that only showed up when bison products generated on FC5
were compiled on Windows. (Fixed promptly by Roland McGrath.  Thanks 
again.).

These tools need extra care when updating.
