Slimming down of gcc binaries

As I promised in earlier post, I wrote an article about reducing executables size created with gcc 4.3.x (cross) compiler.
It might be useful for people writing games/demos ‘near bare metal’ (close to the hardware) and with standard system calls (BIOS/XBIOS and so on). It’s now possible to use gcc even for lower spec machines like Atari ST (512kb RAM), where every byte is precious. Before this gcc 4> binary size was a real problem for standard machines.
