--- Comment #5 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed. Similarly to other bug reports involving warnings and macros
defined in system headers this too is caused by -Wno-system-headers and the
macro NULL being defined in system headers.
$ cat uu.c && /build/gcc-trunk-svn/gcc/xgcc -B /build/gcc-trunk-svn/gcc -S
-Wsystem-headers -o/dev/null uu.c
#include <stddef.h>
const char* a[1] = { "", NULL };
In file included from uu.c:1:0:
uu.c:3:26: warning: excess elements in array initializer
const char* a[1] = { "", NULL };
^
uu.c:3:26: note: (near initialization for ‘a’)
