A recent article in a Linux magazine talking about winelib mentioned
using __attribute__((com_interface)).  I thought that attribute
was no longer valid in gcc.  The reason I am asking is because I
am trying to do COM development using mingw, C++, & (hopefully)
WIDL.  I thought the 3.x and higher version of gcc supported
-fvtable-thunks by default making it binary compatible with windows
COM.&nbsp; Does anyone know if this is really true?<br>
