 since c11 mode is not being enabled via `-std=c11`.

 using std=gnu99 doesn't make gcc11 happy:

 {{{
 $ cat arraytest1.c
 typedef unsigned int uint;

 int main(void) {
   const uint keys_to_ignore_count = 1;
   char * keys_to_ignore[keys_to_ignore_count] = { "id" }; // ID is allowed
 ot mismatch
   return (0);
 }

 $ /opt/local/bin/gcc-mp-11 -std=gnu99 -c arraytest1.c
 arraytest1.c: In function 'main':
 arraytest1.c:5:3: error: variable-sized object may not be initialized
     5 |   char * keys_to_ignore[keys_to_ignore_count] = { "id" }; // ID is
 allowed ot mismatch
       |   ^~~~
 }}}

 I haven't tried any other compilers.
