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 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.
