Iain Sandoe <iains at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2019-09-23 Ever confirmed|0 |1 --- Comment #11 from Iain Sandoe <iains at gcc dot gnu.org> --- current trunk builds fine on 10.14 with the 10.14 SDK in the 11.0 command line tools. It looks like the 10.15 SDK will need a patch to work around our missing __has_xxxx() e.g. comment #5. I'm testing that (on 10.14) and will apply it as band-aid if the results are satisfactory.
