A manifest won't help here, because it'd have to be embedded in
python.exe or named python.manfest next to python.exe (I think).

I'm just sort of against platform specific functions as a matter of
principle when they can be avoided. (e.g., Many of the iphone ones, to
me, could easily be platform ones. Things like al_get_battery_level()
could apply to a laptop, etc.)

Another way to resolve this would be something like:

al_register_library_loader(proc /* user written callback */);

bool proc(const char *name, char *folder, int len)
  // name [in] => name of file being loaded. could be used to
determine which folder is relevant
  // folder [out] => place to find library
  // len [in] => folder buffer size

  strcpy(folder, "c:/myfolder");

  return true; /* use this folder */

Any time Allegro needs to load a library, it would use the first
folder set by a proc that returned true.

Not sure if this type of thing applies to Linux / OS X as well, but
the above could solve it for all platforms. But if this is only ever a
Windows problem, then the above is just over engineering.
