Summary: Dynamic linker can't find _al_managled_main with XCode4

Initial Comment:
The XCode4 Developer Preview has -fvisibility=hidden on by default, which makes the dynamic linker unable to resolve it at runtime.  This option is good for both launch time and optimization, so it's desirable to have it on.  Given that, please consider adding "__attribute__ ((visibility("default")))" to the OS X declaration of _al_mangled_main.

Message:
Does Allegro compile with -fvisibility=hidden at all? We don't set any
symbols to __attribute__ ((visibility("default"))) from what I can see. And
all non-public functions are declared static anyway. (Functions starting
with _al_ are public if user code includes any of the allegro5/internal/*
headers.)
