OK, thanks.  Yes, that's better.  I had thought to avoid the extra
quoting `\$SCOABSPATH' so that it would be invisible to the user from
the libtool output, but the way that is now is ok with me.  However,
it's a good idea not to carry this into CVS HEAD for another reason:
Sometime after 2.0 I may want to reform the quoting stuff a bit, both
to allow file names with spaces and possibly for efficiency.  Above
may not work any more then.


I went over the patch once, and installed it after a few small
modifications:
- use `test' instead of `[ ]'
- reformat comments a bit, fix typo execurity -> security
- fixed quoting of allow_undefined_flag (use single quotes so the
  expansion occurs in libtool, not in configure).

A couple of open questions remain:
- was the quoting for allow_undefined_flag different on purpose
  (i.e., because of some bug in ltmain)?
- the archive_cmds and archive_expsyms_cmds do not make use of
  allow_undefined_flag at all (they used to do so before),
  that makes its setting ineffective.
  Could you be bothered to post a followup patch to fix this
  (including ChangeLog entry, if possible)?

Here's what I installed.  In a followup patch, I'll remove the
now-unnecessary cruft from AC_LIBTOOL_LANG_C_CONFIG.  :)

Cheers, and thank you,
Ralf
