From 9dbe6d3478329df159cf402c1812485649741e7c Mon Sep 17 00:00:00 2001 From: Mattias Andrée Date: Sun, 20 Dec 2015 15:54:26 +0100 Subject: It is of course possible that int is 16 bits, and long is required to get 32 bits (in this case, assuming 8-, 16-, and 32-bit integers exists) long must be 32 bits.
