And for the info : 
http://www.opengroup.org/onlinepubs/009695399/basedefs/sys/types.h.html :
The implementation shall support one or more programming environments in 
which the widths of blksize_t, pid_t, size_t, ssize_t, suseconds_t, and 
useconds_t are no greater than the width of type long.



So it can be even worse : depending on some configuration ("programming 
environments"), the size of ssize_t can change...
