/* With revision 124583, using compiler command "./xgcc -B./ -O -S ~/qual.c"
   in the "prev-gcc" directory once it's been updated with the current
   binaries, the compiler complains:

   qual.c:11: warning: passing argument 1 of 'foo' discards qualifiers from
pointer target type

*/
typedef unsigned char block[8];
extern int foo(const block *in, block *out);
int bar (const void *p, void *q) {
  return foo (p, q);            /* line 11 */
}

I'm not 100% sure about how array types and qualifiers mix, but I believe this
is correct code, and that there shouldn't be a warning.
