I was thinking that the compiler itself is always built just the
compiler flags, "-O2 -g", i.e. BOOT_CFLAGS.  The thought occurred
to me that if it weren't for debugging issues we could use -O3 or
-fomit-frame-pointer.  Then it struck me that this might be an
excellent case-study for Scott Robert Ladd's genetic algorithms.
Are there any optimizations that should be explicitly enabled or
disabled during bootstrap, to produce a faster compiler.

I'm working on this very thing at the moment, but it requires a somewhat different approach from the one I took in the original Acovea. If someone is willing to lend me some cluster time, I could speed up my analysis... ;)
