found the issue ( I think )

I had run configure with --host=none and that was a problem.

I tried again with :

../gmp-4.3.1/configure --host=sparcv9-sun-solaris2.8 ABI=64
--prefix=/opt/csw --enable-cxx

and it all builds to completion.

The next issue is getting the tests to run clean, I keep hitting these :

/opt/csw/gcc4/bin/gcc -DHAVE_CONFIG_H -I. -I../../../gmp-4.3.1/tests/mpn
-I../.. -I../../../gmp-4.3.1 -I../../../gmp-4.3.1/tests 
-I/opt/csw/include  -m64 -mptr64 -Wa,-xarch=v9 -mcpu=v9 -mno-app-regs -g
-Qy -c ../../../gmp-4.3.1/tests/mpn/t-asmtype.c
ld.so.1: cc1: fatal:
/export/medusa/dclarke/build/LIBGMP/sparc_v9_gcc/.libs/libgmp.so.3: wrong
ELF class: ELFCLASS64
gcc: Internal error: Killed (program cc1)

which is odd.

I'm still digging into this.
