Okay that's a relief.  Thanks.

At a slight tangent;  maybe m4sh could provide a shell function calling macro
(off the top of my head):

# AS_CALL_FUNC func_name [args ...]
# ---------------------------------
AS_DEFUN([AS_CALL_FUNC],
[_as_save_positional_params=$${1+"$$@"}
$*
eval set -- $$_as_save_positional_params
])

Doesn't the exit actually terminate the script for (at least) some shells?

BTW, we're thinking of moving the generation of ltmain.sh to m4sh when the
shell function support in autoconf pans out...

Cheers,
        Gary.
