When I tried this last week, changing -m32 to -m64 got me a clean 64-bit
build of dmd2, with no build errors.  Very easy.

A caveat-- I tried the same search and replace s/32/64/ in places on the
druntime and phobos makefiles, but there was something more subtle going
on--the generated libraries built fine but were still 32-bit objects inside
the .a archives.  Somehow I wasn't passing the right flags to generate
64-bit libraries.

Is there a flag to tell dmd to compile to 64-bit objects?

Thanks,
Jason
