Comment (by sambthompson):

 Thanks, Joshua; that worked (with matching `#endif`). I was expecting
 `MAC_OS_X_VERSION_MAX_ALLOWED` to be set higher since the port supports
 it, but clearly this is also constrained by the build compiler/SDK
 version, which is great. Hopefully this can be upstreamed and the Portfile
 adjusted again to reflect building works for 10.14 and 10.15 (there is
 still #69440 for 10.12 and 10.13).
