I've got a fully working version now. I set USING_OPENGL_VSYNC in configure 
instead of using that line in mythfrontend.pro, and everything built as 
expected with the #ifdefs in place. However, I think the problem is more 
accurately fixed by changing the line in mythfrontend.pro from



using_opengl_vsync: DEFINES += USING_OPENGL_VSYNC

I'm rebuilding that way to test now.

Not sure what to say about the connect portion. Its working for me right now 
w/it in there, but I started w/this patch on cvs head, not 0.18.1.
