Commit 56be47f87629e31afbcb0774aa65735f539ee972

Fix a warning on 64-bit Windows When sizeof(size_t) != sizeof(unsigned), adding a size_t to cif->bytes produces a "possible loss of data" warning. However, the size_t in question refers to the size of a single parameter. Use a cast to avoid the warning.
