This is the latest install-sh in the Automake CVS.
So this bug report belongs to bug-automake, where I'm forwarding it.

I looked at POSIX, and 'trap - 0' is standardized, while 'trap 0' is not.

The Autoconf manual doesn't mention this protability problem; would you
be so kind to provide details about your setup (which OS, which shell, and
its versions)?  I'd like to add the info to the manual.  (Ccing to
bug-autoconf, too.)

If "trap - 0" doesn't work on your system, would "trap '' 0" work?
Or perhaps "trap : 0"?

Have a nice day,
