Re: GtkGlArea port to GTK+3 : RFYC

[Tarnyko <tarnyko tarnyko net>]

Hey, that's interesting, thanks John ! 

BTW, and for google too, to generate the configure script under Win32, I was 
required to remove all mention of GOBJECT_INTROSPECTION and GTK_DOC macros 
from the Makefile.am files. Then run : 

autoreconf --install 

and it builds and runs just fine. 

Regards,
Tarnyko
