Xenix 386 will run/link executable/object files in its native format
or in AT&T's COFF (Common Object File Format) format.

Most SysV R3.2 386 ports will run/link both COFF and Xenix binaries.

Does anyone know if there is any AT&T-mandated policy that all Sys VR3.2
386 ports run COFF binaries, Xenix binaries, or both?
