Thanks!

I have a couple of minor comments:

Shouldn't we support the -v option defined by the Posix draft?

If you are using binary search, isn't it better to call bsearch?

Finally, a general remark that is not directly related to the code.  A
few ported packages include a fake getconf script which just exits,
because the configure script invokes getconf.  When getconf is
included in djdev, people who work on these packages should remove
those fake scripts and use the real getconf instead.  (I know it's too
early to talk about this; I just wanted to go on record about this
before I forget.)
