How does libc handle it? It must define it somewhere (at least I assume 
so, because there is no linker error if a program doesn't provide it) but 
it can be overridden at will. I have a feeling that might be because libc 
defines it to be zero, but in that case my definition in Allegro ought to 
work the same because I'm currently just zeroing it to force the non-move 
sbrk() algorithm...
