Hi! Gary Vaughn pointed me at gnulib for portability experts.
I've been working on some portable shell scripting material. I'm trying to
track down the details of a couple of "some systems can't..." comments from
the Autoconf documentation, because I haven't been able to find any such
systems.
I am looking for systems on which the following *do not* work:
unset
"$@" (expanding to null, not an empty string, when no positional parameters)
shift N
getopts
set -- args
I had been using Solaris's shell as the "oldest shell I can still find", but
all of these work in it.
(As is so often the case, "portable" is not exactly a boolean; what I want to
be able to do is tell people not just that there exists a machine where
one of these doesn't work, but what it might be, so they can make informed
decisions about it.)
