Inaccurate/inconsistent output from mpf_out_str

[Yihang Ho]

Hi Leif,

Ah, that solves the problem. Thanks!

Anyway, just curious, why is this even happening? AFAIK, I didn't have GMP
installed (it's a fresh Ubuntu VM). In fact, before make install (or after
make uninstall), my code won't even compile. After make install, my code
compiles, but says version 6.0.0. After ldconfig, it it goes to 6.0.99. Any
idea why 6.0.0 appears in the first place?
