mpn/gcd_1.asm fails to build on Solaris 10 SPARC 64bit with Studio 12.3 cc - SOLVED

[Mark Ashley]

I can appreciate the nuances in GMP, it's not obvious though to casual
builders such as myself what it needs (and doesn't need), hence the point
of this discussion and putting it into the archives for google to find
later. I'd have found it very useful three days ago :)

Because my GMP packages will be downloaded and used by tens of thousands of
others I might re-compile with ABI=64, --disable-assembly for SPARC and
--enable-fat for x86, thereby providing the widest possible platform
support. Speed isn't a big factor, portability is. Let me know if that
seems outrageous.
