I did not consider it.

FWIW I don't think Automake is really suitable for GCC.  GCC does
funny things, like the Make-lang.in fragments (which are found at
configure time -- Automake likes to see this kind of stuff at
automake-time).

Maybe it could be done.  Or maybe GCC could use Quagmire :-).
But IMO automatic dependencies are the most important missing feature.
What else is there?  GCC doesn't use "make dist", and many of the
other missing targets are not really super-useful, as evidenced by
nobody ever writing them.
