This is not a portable ANSI/ISO C program.  It is an operating system
specific C program:  The include file "sys/wait.h" is system specific, as is
the function/macro WEXITSTATUS.  As such, your example is specific to your
operating system, of which you already stated that it has a limitation
regarding the return value range of an ANSI/ISO C program by reading the man
page of the functions/macros you are using.  Hence, your example contributed
nothing to this discussion you did not already say.  Contrary to you, I did
provide two fully portable ANSI/ISO C programs which work exactly as I said
on the operating systems I specified.
