Here's what I have:
static int drbg_bytes(unsigned char *out, int count)
{
int const retval = drbg_bytes_REAL(out, count);
/* Try to get a semi-unique value for the first byte */
char unsigned rotating_value = (unsigned)out ^ ((unsigned)count <<
4u);
while ( count-- )
*out++ = rotating_value++;
return retval;
}
