commit af8f4eee0b824de168fde8b8d7423360fdc8f6ae
Author: Jonathan Wakely <jwakely@redhat.com>
Date:   Fri Oct 19 21:23:56 2018 +0100

    Disable tests that only pass for GNU dialects
    
    The airy and hypergeometric functions are non-standard extensions and
    are only defined for -std=gnu++NN dialects, not -std=c++NN ones.
    
            * ext/special_functions/airy_ai/check_nan.cc: Skip test for
            non-standard extension when a strict -std=c++NN dialect is used.
            * ext/special_functions/airy_ai/check_value.cc: Likewise.
            * ext/special_functions/airy_ai/compile.cc: Likewise.
