is WIDL a sutable replacement for microsoft MIDL?

[Jonathan Wilson]

Could WIDL be used alongside MingW to generate IDL files on windows?
What changes, if any, would be needed to WIDL to get it working on win32 
and compiling IDL files in a way that MingW can use?
Does MingW have enough of the OLE header files for WIDL to work?

Having an IDL compiler for MingW would be a very usefull thing for those 
doing COM development IMO.
