Please report them in a separate bug.  Mostly they are GCC bugs, but
once in a blue moon we find a real problem.

> For example:
> 
>   In file included from keyboard.c:25:0:
>   keyboard.c: In function ‘reorder_modifiers’:
>   lisp.h:377:40: warning: potential null pointer dereference [-Wnull-dereference]
>    #define lisp_h_XCDR(c) XCONS (c)->u.s.u.cdr
>                           ~~~~~~~~~~~~~~~~^~
>   lisp.h:1308:10: note: in expansion of macro ‘lisp_h_XCDR’
>      return lisp_h_XCDR (c);
>             ^~~~~~~~~~~
>   lisp.h:376:38: warning: potential null pointer dereference [-Wnull-dereference]
>    #define lisp_h_XCAR(c) XCONS (c)->u.s.car
>                           ~~~~~~~~~~~~~~^~
>   lisp.h:1302:10: note: in expansion of macro ‘lisp_h_XCAR’

This is master, right?
