You should send a bug report following the instructions in the GMP
manual.

It's a little hard to read this (a complete compilable test program
would have been nice), but if I understand the figures correctly, you
get gcd(0,1) == 1 on linux/x86 and gcd(0,1) == 2 on hpux. Then the
hpux result is incorrect.
