Por ahi encontré un mini compilador de C mucho mas chico que el gcc:
http://fabrice.bellard.free.fr/tcc/
Tiny C Compiler - C Scripting Everywhere - The Smallest Linux C Compiler
Features
SMALL! You can compile and execute C code everywhere, for example on rescue disks (60KB for x86 TCC executable).
FAST! tcc generates optimized x86 code. No byte code overhead. Compile, assemble and link several times faster than 'gcc -O0'.
UNLIMITED! Any C dynamic library can be used directly. TCC is heading torward full ISOC99 compliance. TCC can of course compile itself.
SAFE! tcc includes an optional memory and bound checker. Bound checked code can be mixed freely with standard code.
Compile and execute C source directly. No linking or assembly necessary. Full C preprocessor included.
C script supported : just add '#!/usr/local/bin/tcc' at the first line of your C source, and execute it directly from the command line.
