To inner_expand or not to inner_expand; that is... (was: More on problem with makefile variable expansion)

[Ray Simard]

OK, found the code block to handle inner expansions if the
inner_expand option is set. Looking through automake and
Variable.pm, it seems that inner_expand is never set. That
is what was causing the problems.

If I read the Variable.pm man page correctly, inner_expand is
supposed to be on by default. Is that accurate? If so, is
there any reason why the following patch would not be
appropriate?

Thanks for any help.
