Use isnan, isinf, isfinite, signbit functions from C++ std lib. These functions are guaranteed to be part of the std lib since C++11 which is now a requirement of Octave. * configure.ac: Remove OCTAVE_CHECK_FUNC_CMATH checks for isnan, isinf, isfinite, signbit. Remove AC_CHECK_FUNCS tests for finite, isnan, isinf, signbit, _finite, _isnan. Remove AC_CHECK_DECLS test for signbit. * acinclude.m4 (OCTAVE_CHECK_FUNC_CMATH) : Remove unused macro. * lo-mappers.cc (isnan, isfinite, isinf): Change functions to delegate to std::FUNCTION of the same name rather than possibly calling lo_ieee_FUNCTION. * lo-ieee.h: Add #include <cmath>. * lo-ieee.h (__lo_ieee_isnan, __lo_ieee_finite, __lo_ieee_isinf, __lo_ieee_signbit, __lo_ieee_float_isnan, __lo_ieee_float_finite, __lo_ieee_float_isinf, __lo_ieee_float_signbit): Change functions to delegate to std::FUNCTION of the same name. * lo-ieee.cc (__lo_ieee_isnan, __lo_ieee_finite, __lo_ieee_isinf, __lo_ieee_signbit, __lo_ieee_float_isnan, __lo_ieee_float_finite, __lo_ieee_float_isinf, __lo_ieee_float_signbit): Delete functions.
