--without-cpp11 doesn't help me. I still have the following error

cpl_conv.cpp:2060:9: error: use of undeclared identifier 'isnan'; did you
mean 'std::isnan'?
    if( CPLIsNan(dfAngle) )
        ^
/Users/sean/code/frs-wheel-builds/parts/gdal__compile__/gdal-2.2.0/port/cpl_port.h:687:23:
note: expanded from macro 'CPLIsNan'
#  define CPLIsNan(x) isnan(x)
                      ^
/usr/include/c++/4.2.1/cmath:551:5: note: 'std::isnan' declared here
    isnan(_Tp __f) { return ::__gnu_cxx::__capture_isnan(__f); }
    ^
1 error generated.


I'd love to be able to build 2.2.0 on this slightly out of date compiler,
but if 2.2.0 will require C++11, I'll get with the program.
