Well, see, it would not surprise me if gcc's configure.in turned out
to fall into the 'pathological' category. And if we're going to fix
it, I'd rather cut over to the new mechanisms completely than waste
effort making both releases happy, which will then be thrown away when
the real 2.50 comes out. (But we can't do that in mainline.)
Hm, maybe what we need here is a CVS branch for configury work.
