 Hello Ralf,
after this patch all tests from the old test suite are OK.

The new test suite still shows some problems but its getting much better:

----------- snip --------------------------------------------
## ------------- ##
## Test results. ##
## ------------- ##

ERROR: 103 tests were run,
13 failed (3 expected failures).
17 tests were skipped.
## -------------------------- ##
## testsuite.log was created. ##
## -------------------------- ##

Please send `tests/testsuite.log' and all information you think might help:

   To: <address@hidden>
   Subject: [GNU Libtool 2.2.11a] testsuite: 42 54 73 76 77 84 100 101
102 112 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'.
----------- snip --------------------------------------------

I have attached the whole log file.
