I have no objection :-)

It does occur to me that perhaps we should explicitly say that you
have to use GCC to build a cross GCC, because non-C front ends may
make use of ISO C constructs and GCC extensions.

Or else we should root out all the GCC extensions from the non-C front
ends, and hold all the code to K+R compatibility.  Which might be
easier to explain and enforce, down the road.
