Joseph,

Hi, sorry for the troubles! I am having difficulty seeing this fail on
my system.  I built gmp from upstream, installed it, and pointed to
the install location with --with-gmp. Which stage does your build fail
at?

I am actually not totally sure how to respect the -with-gmp argument
in libcc1.  auto* tools are not my strongest skill. ;)

I notice gcc/configure.ac I think just exports the variables to
Makefile.in from the main configure script.  That what we should do in
this case?

Cheers

Phil
