However, some testing with the mingw cross-compiler reveals that it is

I thought the point was that we wanted the magic main to be in a
static library anyway?
Besides (as I said), there is a patch (on the mailing list somewhere)
that makes it possible to use main() instead of WinMain() on Windows.
IIRC, no special code is needed for MinGW, and MSVC requires a #pragma.
Also, the trick to allow "int main(void)" does not work for C++ as the
prototype has to be declared with extern "C", and C++ does not allow
inexact prototypes as C does.
Ah, maybe C++ was the reason. But I'm not sure I understand: we simply
#define main al_main, then have the "extern void al_main(int, char
**);" in our own (C) source file - so the C++ compiler would not see
this at all?
(I didn't look at your attached patch to verify any of this).
