...Without speaking to any of the other issues of this thread, I can
provide commentary about the above comments; In short, it's not very
difficult to configure a shared installation with as much local deviation
as you wish. We do it here with a great many software packages that were
"never intended" to be managed this way. Here's the go:

Start with an intact, proven working installation directory tree that's on
a served network drive (by whatever means). Then, on each "installation
client" provide a complete directory tree that matches the structure of
the networked tree in every particular, at least in so far as local
modifications are desired. Then, each directory on the client nodes are
populated with links back to the network counterpart. When particular
sections of the tree don't need any local variant, a link can be provided
at the directory level to present entire branches of the directory tree
from the networked installation.

Of course, this has nothing to do with Cygwin, and, now that I think of
it, I'm not sure I've ever done this with a Cygwin-served
(Windows-served) directory tree, but I can't think of any reason why this
wouldn't work just fine in an all-Windows environment.

Hope this helps,
Richard

P.S. Igor, regarding execv(), I had indeed 'malloc'ed just enough memory
for nargv and the extra null was in fact in non-malloced memory! Arg! What
surprised me was that the write to that memory space was permitted and it
failed sometime later when that memory location was needed/used for
something else! (wtf? -frown- )  Tnx, RT P.P.S. My Windows XP Pro
_doesn't_ have ping or dig/nslookup?! -frown-  Tnx again, RT
