I've run the testsuite of libtool in a VPATH build on Solaris 10, using
the C, C++ and Fortran compilers from Sun Studio 5.9 (2010/10/14), with
the patch series posted here applied:

  <http://lists.gnu.org/archive/html/libtool-patches/2011-11/msg00160.html>

Here is the commands I've used to run the testsuite:

  $ mkdir BUILD-sunstudio
  $ cd BUILD-sunstudio
  $ nohup sh -c '
  >   export COMPILER=sun;
  >   export CONFIG_SITE=/usr/local/share/config.site;
  >   ../configure && make && make -k check
  > ' &

Attached are the generated output (`nohup.out'), and the files
`config.log', and `tests/testsuite.log' (compressed).
