in thread Perl printing long long types

You are correct. You CAN get 64 bit functionality on a 32 bit machine. To do that, the GNU compilier uses long longs which are 64 bits. If all that is needed is 64 bit data, then use64bitint should be sufficient. Also, a re-compile would be necessary.

After the recompile, the quad packing will also be avaliable. A Quadword is just what is sounds like: four words. A long is two words, so a long long is four words which is equivalent to a quadword.

    ...long long is four words which is equivalent to a quadword.

    That's pretty much what I thought, but the OP seemed to be making a distinction, and never having used a C compiler on a 64-bit platform, I wasn't prepared to come straight out and state that, hence my question:)
