Does anyone know the current draft status of POSIX.2 with regard to
the system() function and its return code.  I see that SVR4 now
returns -1 on an error (fork, exec, or wait error) while Reno
still returns the exit status of 127.  Is -1 a valid return
value--that is, are -1 and the valid wait() and waitpid() exit
statuses mutually exclusive?
