OK.  Let's find out.

Hmm.  I can't see where convenience libraries are involved here.
In any case: We need more information, see below for a list.

Do you have a link to that discussion?  Maybe it has more information.

Not with C, there aren't, when using Libtool >= 1.5.16.
(If you use any older version: update to 1.5.18, please).

Grab Libtool 1.5.18, post output of `configure' run, config.log, output
of
  make check VERBOSE=x
(please bzip2 or gzip large attachments).

Show how the packages that fail are built: post the relevant
`libtool --mode=link' lines and what they output.  In case you are
unsure what is relevant, post more so relevant stuff is included in any
case.

I bet this is related, it tests dlopening.

Execute
  make check VERBOSE=x TESTS='mdemo-conf.test mdemo-make.test mdemo2-conf.test 
mdemo2-make.test mdemo2-exec.test'
and post the output (This is a subset of the check above).

Just FYI for the other Libtool developers: If Solaris 10 turns out to
need a Libtool update, I can probably do one next weekend.  Blind
guessing makes me believe it's a ld bug rather than a Libtool bug, but
let's not jump to conclusions here.
