That fixes the bug on hosts where int is 32 bits and long is 64 bits, but if I understand the problem you found, then surely the bug remains on hosts where int and long are both 64 bits. How about this further fix? 2006-05-10 Paul Eggert <[EMAIL PROTECTED]> * crc.c (crc32_update): Remove unnecessary L suffix. * md4.c (rol): Cast right-shift arg to uint32_t to prevent unwanted sign propagation, e.g., on hosts with 64-bit int. There still are some problems with reeelly weird theoretical hosts (e.g., 33-bit int) but it's not worth worrying about now. * sha1.c (rol): Likewise. (K1, K2, K3, K4): Remove unnecessary L suffix.
