[OT] gcc-warning: SOLVED!

[Daniel Reuter <reuter@Uni-Hohenheim.DE>]

Hello all there,

In fact, the shortened code I gave you was correct. What was missing in
the original code was #include "bet.h" in main.c, so the prototype for
this function was indeed missing for main, as many of you said. 
I might have come across it in the further development of the program, but
with your help, I could solve the problem really fast, so thanks very much
to all who answered.
Regards,
Daniel
