But not in /usr/lib/libc*.

Exactly the thing I was hoping to point you at with the config message:

Yes.  Unfortunately, there is no trivial
way out of the problem.  I think the proper solution is for guile
(and any other package that installs its own config.h file) to
"prefix" the defines:

 http://ac-archive.sf.net/Miscellaneous/ac_create_prefix_config_h.html

and use those #define-d values from their installed config header.
It would be "good" to prominently document the importance of this
in the autoconf docs.  Meanwhile, we have a problem....

No.  cgi-fsm.c is under CVS because it contains some edited source,
though it is mostly generated.  Looks like I left cgi-fsm.h off the
list of generated source.  Sorry.  It will be updated in a few minutes.
I'll also send it as an attachment under separate cover.

But, couldn't we just look for them in the other common libraries in the
configury before complaining and have the configury set the LIBS value
appropriately?

Yep, that's what clued me in.

So it sounds as if we need to submit patches to libguile, if not done so
already, and argue the case.  However, we might need to update autoconf
documentation first.
