CommonCrypto/CommonDigest is available on Mac and there is function in the libc for MD5 calculation. MD5Final is a C define of CC_MD5_Final. Under some circumstance we have the symbol defined twice in samba binaries on Snow Leopard at least. By detecting CommonCrypto/CommonDigest we end up always using the system version if available.
