>Description:

The file unknwn.h (from windows' api) gives internal compiler error.
I narrowed it down to the following two lines:

--------------------------------------------------------------------------
struct __attribute__((com_interface)) IUnknown { };
struct __attribute__((com_interface)) IClassFactory : public IUnknown { };
--------------------------------------------------------------------------

Works with gcc 2.95.4 but not 3.0.1 and up.
Error message:

foo.cc:2: Internal compiler error in tree_low_cst, at tree.c:3462
