That guess was wrong. The problem turns out to be that lint is defined
in config.h. When lint is defined, Cygwin's <sys/cdefs.h> defines
_Noreturn to be a macro with empty expansion. I've raised the question
on the Cygwin list
(https://www.cygwin.com/ml/cygwin/2016-05/msg00374.html) as to whether
that's a bug.
