I'd like to have a more principled approach to fixing the back branches
than "we'll do whatever it takes to have a clean buildfarm board on the
set of machines that happen to have volunteered to run buildfarm on that
branch".

The geometry test has been such a consistent bugaboo that I'd sooner
remove it from the back branch test lists than follow the path your
proposal leads down.  I can see we'd need at least one more geometry
instance immediately in the 7.3 branch, and what about 7.2?

Agreed --- this is outright unportable code.  Patched in 7.2-7-4.
(It may be that 7.4 fails to fail on your machine because it's already
included <errno.h> by way of c.h, but the extern is an invitation to
trouble in any case.)
