It turns out these failures are a result of using the 2.0n ABI
with gmp-4.2.2. This is the default for hppa2.0w-hp-hpux11.11.
In all my previous testing, I had built GMP using the standard
1.x ABI. Using the 2.0n ABI affects libmpfr.
The 2.0n ABI attempts to exploit the 64-bit registers and
instructions present in PA-RISC 2.0 when using the 32-bit HP-UX
runtime. This is possible because wide HP-UX kernels maintain
a full 64-bit context for 32-bit applications.
I expect this problem affects all GCC versions requiring GMP for
this target.
