Has anyone been able to get DWT to compile with GDC?  I keep getting lots of errors, particularly with OBJIDL.

"import\dwt\internal\ole\win32\OBJIDL.d:39: Error: identifier 'DWORD' is not defined"

I thought the error may be cause by circular linking problems so I tried compiling with "-fonly=import\dwt\all".  This just results in the compiler crashing.
