[sr #108201] libtool problems with -export-symbols-regex on solaris with gcc-4.7.x

[Richard PALO]

Follow-up Comment #5, sr #108201 (project libtool):

Here is my feable and first attempt to detect the problem using the
testsuite.

First, the test export.at seems to work by default, but it is only a gcc
(simple 'C') test:

1 test was successful.

I updated this test as follows (unsure about this test on other than an
elf-based platform):

Please send per-test log files and all information you think might help:

   To: <address@hidden>
   Subject: [GNU Libtool 2.4.2] testsuite: 45 failed

You may investigate any problem if you feel able to do so, in which
case the test suite provides a good starting point.  Its output may
be found below `tests/testsuite.dir'.

gmake: *** [check-local] Error 1

I'll append the testsuite.log to show the absence of SONAME.

I guess I don't know enough about libtools testsuite system to get this
invoked with the CXX tests...
