sunnycoderCommented:
which compiler/platform? Can you give exact error message and point out the line at which it is indicating the error ... normally this error is seen on old C function definitions where parameter types were declared after function signature.

Infinity08Commented:
In your header file, you are missing a ; after the mouse function signature :

>>         void mouse(int button, int state, int mx, int my )

Check for other similar errors if you keep getting similar error messages.

K&R style function parameters cause a lot of difficult to pinpoint errors (like this one).
