As explained: because it makes it impossible for users running old systems
with pre-C99 compilers to build gcc and thereby excludes them from the world
of free software, which is the opposite of what we're trying to achieve.

The benefit of saving three keypresses is outweighed (for the FSF's goals)
by the disadvantage of excluding a whole category of potential
users/contributors.

That's a purely religious opinion!
You might find it interesting to browse the gnu coding standards
(http://www.gnu.org/prep/standards/) and the additional standards specific to
gcc (http://gcc.gnu.org/codingconventions.html), since much of what we have
discussed is explained there along with the rationale that justifies the
decisions.
Things won't stay like this forever, and at some point we'll undoubtedly
decide that it's no longer necessary to stay backwardly compatible all that
far back, and start using C99 features (and beyond that, we may at sometime
start using C++ in the compiler core). It's a purely practical matter of
ensuring gcc is accessible to the greatest possible number of people.
