This won't work very well in practice, because practically speaking, a GCC recent
(4.4, 4.5, or 4.6) compiler with -O1 optimization has a compile time which is quadratic
with respect to the function size.
Compiling a single 100 0000 C statements function with GCC take a lot of time & memory.
(You might use http://starynkevitch.net/Basile/manydl.c to measure that)
Cheers.
