FWIW, I bootstrapped a pure 64-bit gcc-4.7.2 on Solaris 10/SPARC64 yesterday,
with C, Ada, and C++, using a normal 32-bit-but-64-bit-capable gcc-4.7.2 as
host compiler.  About the only issue was that I had to coerce the host compiler
to generate 64-bit code by default; for that I put

#!/bin/sh
exec gcc -m64 "$@"

in a "gcc64" shell script and passed the path to it in CC when configuring gcc.

Overriding CFLAGS might have worked too, but I didn't try that.
