No worries.  Thank you for taking the time to reply.  

This page:

https://discussions.apple.com/thread/8127677

suggests two workarounds:

Adding gcc option -U__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__

or

Adding gcc option -mmacosx-version-min=10.12 (from gcc6)

I chose the latter and added it to CFLAGS.  It compiled cleanly.

Cheers,
