That's right. And preferably with a configure time option to use the
real GMP if available.

Even dropping only the GMP dependency is one thing less that can go
wrong. 

One user of interest is gcc. As far as I understand, it uses mpfr and
mpc (for complex arithmetic) for constant propagation. Which means
pretty small numbers, and the time spent on this arithmetic is likely a
very small proportion of the compile time. Using the real GMP when
easily available is nice, but it's also massive overkill.
