Well, my concern is coverage.  If it's just me that isn't getting the
.pc for apr-1 with the distro package then I'm all for it.

It's not that the tool doesn't compile, but that it doesn't seem to be
in use for dependent packages in some cases.  I have apr installed
from the distro on 2 boxes but there's no .pc for it on either.  I'm
not saying it won't work in some cases, or even that it's not a good
thing, just that there are probably going to be holes.

If others out there (nudge-nudge, everyone) would like to test it then
I see no reason not to try.  Sorry if I came off all jumpy-like, but
it isn't working for me.

I wasn't suggesting you were, but unfortunately my first tests (apr on
fw1 and my desktop) failed.  That makes me very leery of depending on
it as the "right way" to get compilation settings.  Maybe my boxes are
just whacked out, though... that is entirely possible.  ;)

Is it trivial to have the makefile attempt pkg-config? if so, and it
won't fail the build (may just be a matter of redirecting stderr to
/dev/null), let's try it out.  If it ends up working then
_LARGEFILE64_SOURCE-from-env is just belt-and-suspenders and everybody
wins.  :)
