In the no-good-deed-goes-unpunished department ... drongo is now spewing
a boatload of these warnings:

C:\\Program Files (x86)\\Windows Kits\\10\\include\\10.0.18362.0\\um\\winbase.h(9305): warning C5105: macro expansion producing 'defined' has undefined behavior

Looks like this comes out once per .c file -- probably it's
in an inclusion from <windows.h>. Dunno if there's anything
we can do but ignore it. I wonder though why we have not seen
this on other buildfarm animals.

regards, tom lane
