// JKC:
// This is completely the wrong way to test for new stdlib (supporting std::hash etc)
// We should instead use configure checks or test if __cplusplus is bigger that some value.
//
// On the other hand, as we are moving to wxWidgets 3.1.1, macOSX 10.7+ is required.
// And we could just assume/require building with C++11 and remove the body of this
// ifdef - i.e. no longer support those workarounds.
//
// Macports have provided some really useful information about possibilities for
// building with newer compilers and older SDKs. So the option of building with old
// compilers and old SDKs may not be needed at all, making the shift to requiring
// C++11 have little to no downside. So as of 13th April 2018 the code in this
// ifdef's days are numbered.
