Linking sdl-demo/sdl_main.rs fails #126

Hi, I'm trying to run the demo using the sdl_main.rs approach, but it does not seems to be working. This is the linking error I got:

error: linking with `cc` failed: exit code: 1

This is the Rust version I'm using:

rustc 0.11-pre-nightly (a5cd502 2014-04-22 02:06:35 -0700)
host: x86_64-unknown-linux-gnu

Running the main.rs demo worked fine. Any ideas?

I'm not sure about the current state of sdl_main.rs, especially because I don't have a Mac machine at my disposal. libSDLmain.a is primarily a means to get the consistent SDL_main entry point across different platforms anyway, so you can just use main.rs to build it on Linux anyway. I'll keep this issue open as the whole SDL_main business should be reconsidered at some point.
