You can add the following code to "allegro.h":

#ifdef __WINDOWS__ /* Not sure about __WINDOWS__ define. */
int _Wrapper_for_main ();
#define main _Wrapper_for_main
#endif

And then in WinMain either include "allegro.h" and call `main' or call
`_Wrapper_for_main' directly.  This code in the header should be
inside `extern "C" {}' construct and user program must include
"allegro.h" in the module which declares `main', but I think that
including "allegro.h" in every file in project is required, as it may
provide compatibility between different platforms.

Users might be confused by getting error messages from compiler
that point to `_Wrapper_for_main' which is not in the source file, so
this wrapping can be documented somewhere.
