I have managed to build gcc-gnat 3.3.2 for Sparc/Solaris 9 but there is 
no support for 64-bit.

I pass -m64 to gnatmake and the following error messages appeared:

I believe my gcc-gnat 3.3.2 does not support 64 bit. How do I check? How 
  do I build gnat with 32- and 64-bit support? What have I missed?

Thanks.
