> Guess the SVID/SVVS must not be picky about setpgrp() behaviour.

The setpgrp() in libc.a on HP-UX fully conforms to SVID.

To support job control functions, we added a system call named
setpgrp2() that does what BSD setpgrp() does (except that we
added some needed security checks).

To make it easier to compile BSD programs without changing your source files,
we also provide a routine called setpgrp() in libBSD.a; that routine
just calls setpgrp2().

POSIX will avoid this by not specifying a function named setpgrp(),
but naming both sets of functionalities something else.

Thanks for the encouragement.  I'm glad you're pleased.
