haskellPackages.SDL-ttf: fix build on darwin SDL_main.h which is included from SDL_ttf.h contains a #define which redefines main to SDL_main. This has to do with the way SDL binaries are linked and executed on darwin which is explained here [1]. However this is bad news for hsc2hs intermediate C sources which in this case only to gather version information from the headers and not to run a full SDL application. Thus compilation would fail due to this issue which we can avoid by redefining main to main again after including the header. [1]: http://www.ariis.it/link/repos/sdl-bindings/hssdl-image/MACOSX
