Have you used optimization switches like -O3 or -Os?
This is what the command line help (gcc -v --help) says about them:
  -O<number>                  Set optimization level to <number>
  -Os                         Optimize for space rather than speed
I usually use these to build releases together with -s (strip).
Also I recently switched to MinGW 4.4.0 and the binaries are somewhat 
smaller than in version 3.
I hope this helps you,
