If lint is defined, then /usr/include/sys/cdefs.h defines _Noreturn

Simple test case:
$ cat test.h
#define lint 1

_Noreturn void foo (void);
$ gcc -E test.h | grep foo
void foo (void);

A traditional lint program may not support the new C11 keywords, but
will define the 'lint' symbol. See, e.g.
http://www.unix.com/man-page/FreeBSD/1/lint
But in the present context (see my second message), we're redefining C11
keywords even though __STDC_VERSION__ >= 201112L.
Surely the real problem here is a program which is not a lint executable
defining 'lint' ?
The program is emacs built from a git checkout of the master branch. By
default the configure option --enable-gcc-checking is used, and this
I meant --enable-gcc-warnings.
causes lint to be defined in src/config.h. It doesn't seem to be a
problem on platforms other than Cygwin; or at least it hasn't been
reported.
