I think we should also begin cataloging such portability issues, probably in the autoconf manual... but for now I would like to nail down exactly how much functionality we should expect of our shell functions (HEAD libtoolize uses them extensively for example), and why and where other function features fail.
I've used return in a couple of places (twice with an integer return value), which I fear may break on old platforms. Otherwise I've assumed that all shell variables are in global scope, and that positional parameters are stacked and restored at function call boundaries to an arbitrary nesting limit.
Removing the returns isn't too hard, but if my other assumptions are bad, then 1.6 is in trouble :-(
Cheers,
Gary.
