Re: how to bundle GMP, was: +-Inf and NaN

Maybe a good compromise would be to:
- not bundle GMP with GCL
- use the system's libgmp by default
- but allow the user to specify a specific GMP library when configuring,
e.g. --with-gmp=/path/to/custom/gmp

That would allow users with an older OS to still build their up-to-date GMP
version locally (without installing it, which might cause trouble?) and
make GCL use that.
Or maybe that's already possible with the current configuration script?

Best regards
David
