Under 4.3BSD Unix there is a C preprocessor macro called "unix"
which can be used to control conditional compilation. E.g.,

    #ifdef unix
       ...do some unix dependent stuff...
    #else
       ...do some generic stuff...
    #endif

I do not have access to System V Unix. Is there such a macro under
System V (or something similar).
