Indeed.  Libtool still doesn't support g++ on HP-UX.  It should be
trivial to add support, as soon as you know which commands to use.
A patch for ltcf-cxx.sh Cc:ed to libtool-patches@gnu.org would be very
appreciated.

Hmm...  Could it be because ltconfig doesn't specify a return type for
main() in the `nm' test?

Please try this patch:

AFAIK, mkcheck is a bash-only shell-script.  In any case, this patch
might help.  Please let me know if it fixes the problem.
