--- Comment #32 from Iain Sandoe <iains at gcc dot gnu.org> --- I am being asked (by build systems folks) to make it possible to build back to 10.13 with the current [XC 16] SDKs (which are supposed to support that - but do not include these symbols). This seems a reasonable request and I will test an updated patch.
