They won't matter on older OpenSSL, as the macros will recast
again. But on 0.9.7e the signature is:

void DES_ecb3_encrypt(const unsigned char *input, unsigned char *output,
DES_key_schedule *ks1,DES_key_schedule *ks2,
DES_key_schedule *ks3, int enc);

so it seems to me that with your patch the warnings will appear
on newer OpenSSL. (Confirmed)
