Not sure about Windows, but a quick glance through Stevens' _Advanced 
Programming in the UNIX Environment_ reinforces my off-the-cuff 
recollection that POSIX doesn't specify more than allowing an 8-bit exit 
status code to make it through.  See the wait(2) manual page for the 
documentation for the WEXITSTATUS(status) macro, which on both OS X and 
Linux specifically mention 8-bits.
