Any functions that are not called from a library should not be included
(this is the point of libraries, and that is why they are different to
simply linking with another file).

Allegro includes some "administrative functions" which enable it to work.
For instance, when you call create_bitmap() the function create_bitmap_ex()
is called from within that, which will be included in your program.

It states in the manual that Allegro includes a 200k overhead in any program
just to get the library to work. I suggest you read the manual because it
goes into some detail on the subject of reducing the executable size if
possible.
