Indeed, even if I've been building gmp and mpfr with --disable-shared to
avoid RPATH problems.  One option might be to avoid including gmp.h in
gcc.c in the first place, as I've already mentioned.  I'm not sure how easy
that would be, though.

I've never tried this before (I regularly build with GCC 3.4 as a bootstrap
compiler since I want to include Ada support and that requires an Ada
compiler), but only just received a report from a colleague who tried to
build GCC 4.4 within pkgsrc, but failed in unexpected ways.

Right, sorry: I've tried this with the latest version, gmp 4.3.1.
