System memrchr uses a byte comparison rather than an int comparison.
"The memchr() function scans the first n bytes of the memory area pointed to by
s for the character c. The first byte to match c (interpreted as an unsigned
character) stops the operation. "
See: http://linux.die.net/man/3/memrchr
It's a good idea to do the same thing for compatibility reasons.
