Good that you found it.

A FAQ about typical problems with solaris+gmp would help.

But do you really still need to use the old broken version of the standard 
library? If you have a choice, you should really use -library=stlport4, or 
some other self-compiled standard library like Apache stdcxx (used by 
default in opensolaris and soon shipped with the compiler). Both should 
work fine with gmp without any patch.

I somehow doubt TG will be happy to include such a workaround, but I may 
be wrong. Note that such a workaround should test that 
_RWSTD_NO_TEMPLATE_ON_RETURN_TYPE is defined (hello MPIR...).
