--------------------------------------------------------------

I think the expected values (such as the following conditional compilation directive) need
to be updated for this platform:

file stdcxx/trunk/tests/support/18.numeric.special.float.cpp:
{code}
...
   373  _RWSTD_SPECIALIZED_CLASS
   374  struct limits_values<float>
   375  {
...
   452      static std::float_denorm_style has_denorm () {
   453
   454  #if defined (_AIX)
   455          return std::denorm_present;
   456  #elif defined (__hpux)
   457          return std::denorm_indeterminate;
   458  #elif defined (__osf__)
   459          return std::denorm_present;
   460  #else
   461          return std::denorm_indeterminate;
   462  #endif
   463      }
...
{code}

According to the INFINITY.cpp config test, `std::numeric_limits<float>::has_denorm'
should have the value `denorm_present' on this platform.

> When compiled with HP aCC 6 on HP-UX running on IPF hardware the newly added test [18.numeric.special.float.cpp|http://svn.apache.org/viewvc/stdcxx/trunk/tests/support/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
