Re: ***[Possible UCE]*** Dynamically linking against GMP and MPFR

If you

cc1/cc1plus/etc. wind up dynamically linked against libgmp.so and

simply run it from another system via NFS, and you have not carefully
installed the appropriate versions of GMP and MPFR on that other
system, the compiler will fail to start, getting an error from the
dynamic linker.

I simply dump the required .so into the lib64 directory of my new gcc installation, and tar up the whole thing. I can untar into my own directory on systems where I have no root access. No doubt others do the same.
