Versions 3.5 and 3.51 complies with the UNIX System V Interface Definition for System V, Release 2 (SVR2) in UNIX commands, utilities, and libraries. They have some SVR3 features, such as support of flexnames in the C compiler. Note that "complies with the interface definition" means that it meets the inteface specification; it does not mean "identical." Versions 2.0 and 3.0 were essentially ports of a subset of SVR1. Version numbers in UNIX PC software have nothing to do with UNIX operating system version numbers, because the UNIX PC software includes many modules, like user agent, window manager, terminal emulator, phone manager, etc., that are not part of a standard UNIX operating system. -- C.
