Yes, that's what i was referring to, and yes.

We do check for DLL compatibility in allegro_init:
if (MAKE_VERSION(ALLEGRO_VERSION, ALLEGRO_SUB_VERSION, ALLEGRO_WIP_VERSION) !=
_get_allegro_version()) {
ustrzcpy(allegro_error, ALLEGRO_ERROR_SIZE, get_config_text("Library version mismatch"));
return !0;
}
Right now, this won't catch the 4.2.1 -> 4.2.0 case, since
_get_allegro_version will return the same number for all stable version
- guess we should adjust that.
