Hi Bernhard, after your commit http://git.uclibc.org/uClibc/commit/?id=067637375658047d70c296606ae17ef0bc86499d tst-cancel7x and others are failing. You changed the getopt handling, but not how the tests are called. http://git.uclibc.org/uClibc/tree/test/nptl/tst-cancel7.c?id=067637375658047d70c296606ae17ef0bc86499d#n35 best regards Waldemar
