Sorry, I have been distracted with other things....

Why is xgcc now dependent on a share libgmp? A FreeBSD gcc does not show any
shared library dependencies other than the standard OS ones. What happens if you
configure the GMP package that is built for gdb with --disable-shared (assuming
it supports it)?

Is gdb picking up a share library reference to it as well?

I have avoided any shared libraries with our tools and I would like to keep it
that way if possible. It is simpler for a number of reasons and what you have
tripped over is one of them.

Another confusing thing is xgcc not using the in tree source for GMP. I assume
that is still present as git master shows it is still in the gcc common recipe.
Is gcc picking up a shared lib over the in tree source?
