Thanks, Simon.
I am old-school: I use only makefiles and gnatmake.
I have re-confirmed that GNAT GPL 2017 and FSF GNAT 8.0.1 both work without 
complaint.

I have this setting: "LINK_OPTIONS = -bargs -static -Sin -largs 
-Wl,-dead_strip -Wl,-dead_strip".

I have tried removing each component of those flags separately; makes no 
difference.

I have tried adding each of -Wl,-macosx_version_min,10.1[123]; makes no 
difference.

Also I do not get messages analogous to your "object file (b~raiser.o) was 
built for newer OSX version (10.13)
than being linked (10.11)" about my own .o files.

What is baffling to me is that it seems to think it is running on macOS 10.11 
even thoughI am running 13.5,
and my XCode and Command Line Tools are all up to date. At least, that is how 
I interpret:
"ld: warning: object file 
(/Users/wf/opt/gnat-2018/lib/gcc/x86_64-apple-
darwin16.7.0/7.3.1/adalib/libgnat.a(s-valuns.o))
was built for newer OSX version (10.12) than being linked (10.11))".

I am also surprised that AdaCoreapparently built a new GNAT on 10.12, when 
10.13 is about to be superseded.

All in all, rather a disappointing performance from AdaCore this time.
