Since 2.5.30 or similar flex now uses GNU m4 to create its output.
Unfortunately up to 2.5.31, it doesn't check if m4 is GNU m4 or not, so when
used on a system which USERLAND is not GNU it fails (with a -P option not found
usually).

Upstream already fixed this in CVS with a complete solution; the attached is
mostly an hack but it's the least invasive thing I can think of.

Thanks,
Diego

P.S.: flex should  have an RDEPEND on sys-devel/m4.
