OpenServer 5 and OpenServer 6 compatibility

[CJ]

I support both OS5 and OS6 SCO customers. I tend to build all
applications on OS5 and distributed to both OS5 and OS6 customers.
This has always worked until I began using pseudo terminals.

I have a "shell" that uses pseudo terminals to drive the application
passed on the command line. When I build on OS5 it works fine. When
I build on OS6 it works fine. When I build on OS5 but deploy and
execute on OS6, getpgid() -- used to insure the application is still
active -- an EPERM (89) is generated by getpgid().

Any ideas?
