That was on my list, but I was taking things slow. That's why I coded
it the way I did ;)  Note that we'll be able to do the same with
APR_FLAG_FUNCS as well, when it's appropriate.

The final tune, maybe, will be to avoid the actual call
to AC_CHECK_HEADERS and hand-code it in, since AC_CHECK_HEADERS
has it's own for/do loop, which we aren't using. There's a part
of me that's hesitant about doing that... although it makes the
configure script a bit uglier, it make it obvious how we are
using AC_CHECK_HEADERS.
