[SDL] Should #include "SDL_main.h" be removed from supporting SDL header files? (was: Mainline vs Embedded)

Can we just explicitly add #include "SDL_main.h" to the test programs?
It seems kind of strange that only those 4 public SDL headers have
that include (opposed to all of them or none of them). It also doesn't
seem like they should really depend on SDL_main. (What does
SDL_audio.h have to do with main, and why does it have a specific
dependency on this, when say SDL_video.h does not?)

It's been a long time (like a year or two ago) so he doesn't remember
the specifics. He said he'll try to recreate it. I think it had
something to do with the fact that the library he was using or MFC
controls the call to WinMain(), but SDL_main.h was trying to redefine
stuff to use the form int main(int,char[]*), and the compiler didn't
like this.
