This breaks the Cygwin build as follows:

image.c: In function ‘gif_close’:
image.c:7342:15: error: ‘GifFileType’ has no member named ‘Error’
     *err = gif->Error;
               ^
image.c: In function ‘gif_load’:
image.c:7675:24: error: ‘gif_err’ undeclared (first use in this function)
   if (gif_close (gif, &gif_err) == GIF_ERROR)
                        ^
image.c:7675:24: note: each undeclared identifier is reported only once for 
each function it appears in
image.c:7684:7: error: too few arguments to function ‘image_error’
       image_error ("Error closing `%s'", img->spec);
       ^
image.c:664:1: note: declared here
 image_error (const char *format, Lisp_Object arg1, Lisp_Object arg2)
 ^
