Hi,

I can't compile dxguid.c in w32api.  The following error happens:

i686-pc-cygwin-gcc [...] w32api/lib/dxguid.c
In file included from [...]/winsup/w32api/lib/../include/oleauto.h:83,
                 from [...]/winsup/w32api/lib/../include/ole2.h:11,
		 from [...]/winsup/w32api/lib/../include/unknwn.h:3,
		 from [...]/winsup/w32api/lib/../include/objbase.h:58,
		 from [...]/winsup/w32api/lib/dxguid.c:28:
[...]/winsup/w32api/lib/../include/oaidl.h:110: parse error before `IUnknown'

It seems IUnknown is used before being defined.  I don't know the *correct*
way to solve that problem but I have a local workaround:

Index: w32api/include/objbase.h

Does that help?
