Don't forget that invoking the gcc executable from make or the shell
involves a fork anyway.  If gcc is 'exec'ed from the script, there will
only be the fork that invokes the shell, versus the fork that would have
invoked the executable.

I was referring to the scripts calling "grep", "sed", etc, to process the
options instead of using the bash builtin commands which don't involve
forks.
