     return GraphicsContext3D::NO_ERROR;

because NO_ERROR is also a macro defined in Windows headers. Ouch.

Also expand this to the (PLATFORM(GTK) && OS(WINDOWS)) combination,
in addition to the workaround for VERSION already present there.

I don't understand why the workaround needs to be duplicated, but LRN confirmed it doesn't build otherwise.

I'll remove the QT thing before landing
