Problem summary

• ****************************************************************
  * USERS AFFECTED: All z/OS C/C++ IEEE users of the math        *
  *                 library using the IEEE only functions.       *
  ****************************************************************
  * PROBLEM DESCRIPTION: The macro __BFP__ used in the header    *
  *                      features.h is incorrect. It is coded    *
  *                      as __BFP. When a function protected     *
  *                      by the above macro is called by its     *
  *                      external name, it results in the        *
  *                      following compiler error:               *
  *                                                              *
  *                      ERROR CCN3023: Expecting function or    *

  *                      Feature test macro _FP_MODE_VARIABLE    *
  *                      is also incorrectly coded as            *
  *                      __FP_MODE_VARIABLE and needs to be      *
  *                      corrected. If not, this will result     *
  *                      in the same error as above.             *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Functions using the __new4105IE macro are affected because it
  checks for the incorrectly coded __BFP__ and _FP_MODE_VARIABLE
  macros. The functions affected are:
  
  acoshf(), acoshl(), asinhf(), asinhl(), cbrtf(), cbrtl(),
  exp2f(), exp2(), exp2l(), expm1f(), expm1l(), hypotf()
  hypotl(), log1pf(), log1pl(), remainderf(), remainderl()
  remquof(), remquo(), remquol(), lgammal()
  
  The problem only occurs if any of the functions are called by
  their external names as given above and when compiled with the
  option float(ieee) or if _FP_MODE_VARIABLE is defined.
  

Problem conclusion

• The feature test macros _FP_MODE_VARIABLE and __BFP__ are
  modified in the features.h header to use the correct forms.
  
  Keywords:
  features.h __new4105IE __BFP__ __BFP IEEE _FP_MODE_VARIABLE
