int main() {
#if __cplusplus == 199711L
    return 1;
#else
    return 0;
#endif
}
compilers/c++: Add MSVC option to make the __cplusplus define accurate Otherwise it always returns the value for c++98, starting with MSVC 2017 15.7 or later. Earlier versions are not affected by this mis-feature. See: https://docs.microsoft.com/en-us/cpp/build/reference/zc-cplusplus?view=msvc-160 This was originally applied as 0b97d585480e973d8b149618901f7a4ddfa1a906 but later reverted because it made the CI red.
