actually this line is the problem (I made this typo in another
place, and corrected it, but overlooked this occurrence).
The "#" should be "$". In a quick grep, I've 50 uses of $ac_includes_default,
with this as the only (current) typo.
If there are further issues, the usual approach for reporting bugs is to
include the config.log and config.status to demonstrate the issue.
