The don't do that because interacting with the real world requires 8, 16, and 32-bit types and C can only represent two of these if `int' is 64 bits wide. (C99 relaxes this restriction such that the implementation is free to create additional integral types of intermediate width, but all must be at least as wide as `char' and no wider than `intmax_t'. POSIX.1-200x unrelaxes this by requiring that types of exactly 8, 16, and 32 bits in width exist; a 64-bit type may exist but is not required.) -GAWollman To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
