This is the correct version of src/libc/ansi/string/memchr.c:

#include <string.h>

void *
memchr(const void *s, int c, size_t n)
{
  if (n)
  {
    const char *p = s;
    char cc = c;
    do {
      if (*p == cc)
        return unconst(p, void *);
      p++;
    } while (--n != 0);
  }
  return 0;
