Thanks for the reply.
I tried changing the target to x86_64-pc-win32 in
gcc_platform_win32.cmake but it still doesn't allow the -m64 option to
I'm thinking about using the powerpc64-unknown-linux-gnu target with
rs6000 cpu_type but I don't know what any of the other
SET are for.
I just need help enabling the -m64 option so I can see the sizes and
offsets of the pointer fields.
