One area it is required, wanted and desired in any C compiler is
for decimal->binary conversions.

Previously GCC had bugs in this area, as it had limited precision
arithmetic, meaning that even conversion of decimal to float had

My bug report:

Of course, having decided to integrate GMP to fix the problem,
they now use it for all kinds of other compile-time transformations.
