Be assured on every proper *nix system   sizeof(int)=4

Only old machines like the Atari ST used 16 Bit integers.

I wasn't quite sure when programming libmediatool. So in
$KDEDIR/include/mediatool.h  you find proper definitions
for 8 Bit, 16 Bit and 32 Bit  types, that work on i386 Linux, Alpha-Linux,
*-BSD and (hopefully) Solaris.
