Okay, I'm implementing this one currently in the moc tool, but even if
they accept the patch it will only appear in the next revision of Qt.

So how should I handle current version of the moc tool?  Should I write
a wrapper similar to depcomp which only uses the new -M{T,D,P,F} options
if the moc is new enough?  Or should I try to do a little bit of
investigation in configure time about the moc (I already have version
information there) and handle the issue with some substitution trickery
in Makefile.in -> Makefile generation time?

Any ideas are welcome,
Gergely
