Use GCC_LINT, not lint

FreeBSD and Cygwin #define _Noreturn to empty if 'lint' is defined.

 You cannot assume that @code{_Noreturn} is a reserved word;
 it might be a macro.
 @item
+When the macro @code{lint} is defined, standard headers define
+@code{_Noreturn} (and therefore @code{noreturn}) to be a macro that

 On MSVC 9, @code{noreturn} expands to the empty token sequence, to avoid
 problems with standard headers that use @code{__declspec (noreturn)}
 directly.  Although the resulting code operates correctly, the
