2776	[fix in git] Failed to wrap classes with virtual inheritance	Alexander Kogan <alexander@…>	Dave Abrahams	"Hi!

I've just generated a wrapper for the simple classes with virtual function and virtual inheritance with Py++ and generated code is failed to compile. Without virtual inheritance everything is ok.

Error log is below, source and generated files are in attachment.
