Aarg, this is the information I was looking for.

Please, Ian, give me a little more trust.  I'm looking for wrong
hypotheses, I'm not trying to make Autoconf selective.

I'm really surprised it doesn't support functions, IIRC I've already
talked to someone about this precise architecture, and he told me that
the simple

#! /bin/sh5

foo(){ unset toto }

toto=tata
foo
echo "{$toto}"

did what was expected.

Still, the presence of unset is a big relief...
