Ok, let's forget that.

It seems to me that's the most sensible solution, at the expense of a
(minor) API breakage though.

So here's the proposition for 4.1.x:
- no (more) magic main on systems that provide the standard main() entry
point (all but Windows),
- if ALLEGRO_NO_MAGIC_MAIN is not defined, 'int main(int argc, char *argv)'
is a valid entry point on all systems and argv[0] contains the name of the
executable (fullname or not); this effectively requires a magic main under
Windows,
- if ALLEGRO_NO_MAGIC_MAIN is not defined, END_OF_MAIN() is required on all
platforms for the sake of portability,
- get_executable_name(buf, size) is removed from the API and replaced by
get_executable_fullname(buf, size, argv[0]),
- USE_CONSOLE defines ALLEGRO_NO_MAGIC_MAIN.
