Sorry I am just now getting to this, but here is my work to get SDL + Opengl in vala working on windows: https://github.com/gorilla3d/Hi-Panda/blob/master/Makefile
It was a painful process. You don't need a main or winmain functions at all. I ended up side loading cygwin, and visual studio libraries (for opengl). Hopefully that helps enough. I also packaged the libraries I ended up using with vala-0.12 http://files.myopera.com/sutabi/vala_game_sdk/vala-0.12.0.zip that may also help.
