[Fan Chun-wei]

Hello Neil,

(Sorry, I forgot to send this patch to the list-sorry for the double-post, oops :|)

OK, here comes the patch for the same purpose using ISO-style varargs...

With blessings, thank you for the reviews!

Subject: [PATCH] cogl/cogl-gtype-private.h: Fix Build on non-GCC

Commit 1b2dd815 (Registers gtypes for all public objects and structs)
introduced GCCism's in its use of varargs, which broke the build of Cogl
on other non-GCC compilers, such as Visual Studio.

Define the COGL_GTYPE_DEFINE_BASE_CLASS and COGL_GTYPE_DEFINE_CLASS macros
using ISO-style varargs so that the build of Cogl can be fixed on non-GCC
compilers.
