In this application, the various DFLAGS are used during compiling to select
between the library functions & header files of the various unixes. Don't
appear to have anything to do with linking.

Lots of compile errors if -DSYSV is omitted.

Changed to LIBS=(nothing)
Suddenly it link works. Yippee.
Just gone back and re-read "man ld", and I still don't understand.

Anyway, well done!

Now to see if I can use it to turn lights on & off....

Thanks to all for your help. Much appreciated.
