I have noticed the following odd behaviour in a program which I just wrote
using DJGPP and Allegro:

I declared a bitmap, (BITMAP *buffer2;) but then never got around to using
this variable for anything.  The program compiles OK but when I execute it,
it immediately terminates, apparantly due do allegro_exit() being called.

Although I have fixed this problem by simply removing the declaration, I was
curious to know if anyone can tell me why this problem occured in the first
place - nothing bad happens if an integer is declared and then not defined.
Is this a BITMAP thing?  An Allegro thing? A DJGPP thing?

All though this is not important, I would like to know if anyone is able to
explain this very odd behaviour.   Thanks :-)
