I have 73 exclude names in one (it also has 30 include names) -- and I
haven't even gotten to putting together the really ugly compile target
yet. Doing the scan for the bulk of the source files to compile is what
takes the most time for me -- I've gotten it "down" to around 5 minutes,
but I know once I throw the other stuff in, it's going to go back up. It
seems to be slowest, the more full-path filenames you have in the
{ex,in}clude names. And there's nothing I can do about not having them be
full filenames, so I'm kind of stuck wrt how long my Ant build takes.
