I tend to agree: I think the answer is no as well.  This issue has
been tested in Autoconf for some months now (Functions Support,
Functions and return Support in m4sh.at), and nobody has reported a
problem.

Anyway, if we're wrong, we can worry about it later.  I don't have any
objection to modifying AS_INIT to check for any set of POSIX sh
features that we like.

Not that I know of.
