Thanks for the detailed explanation. I don't have any background either
on mix 32-bit/64-bit systems nor on Solaris (I was just asked to help to
gcc 3.5 to 4.1.1 on our Solaris server). Therefore my inability to
the ld issue I have with my 64-bit build of GMP.
I will re-read your email more carefully during the day, try what you
and let you know if it worked.
