Where is the GDC binaries for Windows targeting windows?

[Rufus Smith via D.gnu]

http://gdcproject.org/downloads

I've downloaded what I think is the windows binaries targeting 
unknown(windows?). Using VD, it uses gdc.exe, which is not found. 
I renamed exe. Then it doesn't recognize -m64 or -m32 switch.

If I run, from the command line,

gdc main.d

I get

as: unknown option -- mfloat-abi=hard

downloading soft floating point binaries,

as: unknown option -- mfloat-abi=soft

Does anyone actually test this stuff out before it is released?

BTW, main doesn't use any floating point, it's a simple hello 
world... not that it matters.
