As far as I can tell, it already works, in the development snapshots.
I just tried configuring --enable-languages=c, then building via
a straight build, and hardly anything Fortran-like happened, except:

Configuring in i686-pc-linux-gnu/libf2c
creating cache ./config.cache
checking for Cygwin environment... no
checking for mingw32 environment... no
checking for executable suffix... no
checking if compiler f771 has been built... no

Now, were you saying that the *development* version of egcs still
failed for you in this area, or that version 1.1.2 did?  If the
former, please submit a bug report; if the latter, that's because
--enable-languages apparently wasn't supported in that version.

So, I consider this issue closed for now, as things appear to be
working correctly.

BTW, I agree that it's better to put things like this at the configuration
step.  In fact, I think we're going to have to put specifying the
compiler there, and whether a bootstrap-build vs. straight-build is
desired there, as well, when we re-work the configury mess.
