Hmm.. I must have been a bit confused here.. you are correct.

I do. Have seen several old systems where sizeof(int) == 2... none of
these has been running UNIX, or close to being candidates for Squid
however. But still, there is nothing in any standard which says that int
is 32 bits. If we are selecting field sizes optimizing for memory use,
then I think that types with a well defined size should be used, not
types which "incidentally" happens to have the desired size on all known
systems.

My original intent for the sdirno and sfileno fields was to have these
configurable (at build time), to adopt for different setups/uses. The
optimal setup is to have a name space just large enought, and since this
is multiplied with every object in the cache even one byte difference is
quite a lot.
