Hi all,

I have only recently installed djgpp (v2) and decided to port an existing (very simple) graphics program to gcc using allegro 2.2. Everything went very smoothly, however when I compiled using gcc, the executable was 269kb compared to 24kb using Turbo C and my own pixel, line etc functions. I have included my source code (only short) and would appreciate help from anyone who could explain why this occured.

Thanks
