Thanks for the offer.
Does this implementation provide some improvement over the glibc one?
I'd rather not add *any* ftw/nftw implementation to gnulib that
imposes stack-size limitation on the depth of the hierarchies it
operates on.  Since your implementation is recursive, it does that.
You can see the problem by trying to use it on a hierarchy with a
depth of say, 50000.  It'll blow the stack and probably segfault.

The problem is that merely by providing it, gnulib would be
encouraging its use.  People should use fts instead.
