Hi Jeff,
Thanks for the feedback. But I am still suspicious. There are way
too many myths around Autoconf, and I'm willing to believe what I see.
Have you really tried? Ultrix for instance does support the
functions, while nobody would have bet. It just doesn't support the
keyword `function', but on Ultrix for instance, this behaves properly:
#! /bin/sh5
foo(){ unset toto; }
toto=tata
foo
echo ":${toto+set}:"
Also, functions are one issue, another is `unset'. It would be a huge
relief if we could use it.
Why can't we expect sh5 being available?
Still, rest assured, we have no intention to have Autoconf depend upon
shell functions, at least for a couple of years, for the very reasons
described by Paul Eggert: we are the lcd, and aim at remaining it.

PS/ I have a bizarre demand to make: does anybody know a means for me
to have an access to a wide set of old systems?
