+ * The standard macros for converting between host and network byte order are
+ * badly named. So ntohl converts 32 bits even on architectures where a long is
+ * 64 bit wide although the 'l' suffix suggests that it's working on longs.
+ *
+ * So this file introduces variants that use the bitcount as suffix instead of
+ * 's' or 'l'.
