I'm trying to compile a very simple file, main.d:

void main()
{
}

Under Windows 7, 64-bit, with out-of-the-box DMD v2.053 installation. I get this, however:

C:\Users\Me\devl\test>dmd -m64 main.d
Internal error: msc.c 268

x86_64 isn't supported on Windows yet, there should be a better error message though – could you file a bug report?

There is no 64-bit version of dmd on Windows - either for the binary itself or for the code that it generates. On Windows, dmd only produces 32-bit binaries. -m64 should probably be giving you an error message about being unsupported on Windows rather than barfing during compilation, but regardless, it's unsupported because it hasn't been implmented yet.
