OK, but that just makes each warning into an error.  My build terminates
for unused variable "spool_name", which is unused because I don't have
the right configuration.

Not all inline are extern inline, buffer.h doesn't need to be extern
inline, if I understand correctly. But anyway, if you say it's needed,
it's needed.

One more question, is there a list of platforms on which Emacs is known
to build fine, by version? Maybe 25.1 doesn't build on OS X 10.8 for
reasons other than C99 compatibility.
