The main problem is currently that you have to change the Darwin system 
unit, by renaming the "main" procedure in rtl/bsd/system.pp to 
"SDLMain" and then recompile the system unit. Of course, afterwards 
that system unit is only usable to create SDL programs.

So we have to implement a way to specify the name of the routine when 
compiling the program, but that means it must be moved to the main 
program and "generated" inside the compiler. Because it receives 
parameters, this is non trivial (unless I hardcode the parameter 
locations, but that's dirty and non-portable).
