test if an unsigned long fits in a limb.

It's a long list of functions, where a couple of them are supported only
if the platform has the type long long.

I don't think it's a big deal. GMP programs which don't use the lon
glong functions need not care. GMP program which use the long long
functions will fail when compiled on a system which lacks long long. But
then it will fail from various compilation errors long before linking
with gmp..

It may get more confusing if you have a system with several compilers,
where some, but not all, of the available compilers support long long.
Are there such systems? On such a system, ideally gmp configure should
emit a loud warning before using a compiler lacking long long.
