* On some windows machines dirs seem to vanish sometime between

  the call to init_per_testcase (when they are created) and the
  call to the actual test case (when they are used).
* Try to handle systems where crypto is not built better.
  This *is* handled by application, but the test case
  snmp_app_test:undef_funcs could do a better job (which it
  hopefully does now :).
