I had a small program written in C++ in a single file working just fine.
Then I divided the program into three files:
A header file, a source file and a main file.
A part of the header looks like this:

#ifndef Ballshdr_h
#define Ballshdr_h

BITMAP *My_Buffer        // A global declaration for the double buffer

...
...    // Rest of the header
...

#endif

Everything compiles perfectly until I get an error telling me there are
multiple declarations of My_Buffer.
I cannot figure this out as there are no other declarations of My_Buffer.
I've tried changing the name to something else with the same result. I use
the Allegro library, and BITMAP is a struct declared in Allegro.h.

Anyone got a clue as to what is wrong here? I use My_Buffer in both the
source file and in main.

Thanks in advance,

Stian Danielsen
