      Description

      When compiled with HP aCC 6 on HP-UX running on IPF hardware the newly added test 18.numeric.special.float.cpp fails a bunch of assertions.

      One of them look like a configuration problem in the library (has_denorm) while others (min(), max(), and epsilon()) like problems in the test

      $ nice gmake 18.numeric.special.float -r && ./18.numeric.special.float
