/* Get and set errno.  A source file that needs to set or get errno,
   but doesn't need to test for specific errno values, can use these
   functions to avoid namespace pollution.  For example, a file that
   defines EQUAL should not include <errno.h>, since <errno.h> might
   define EQUAL; such a file can include <get-errno.h> instead.  */
