help needed with indexor.c on bsd

[Shan D Duncan]

I recently downloaded a program call indexor [comp.sources.misc vol.7]
 that is suppose to help prepare an index when using latex.  I need
help compiling (if possible) under unix bsd 4.3.  After cleaning up
the source (there was dublicate material inserted into the program) and
getting rid of a syntax error- I still get many redefinitions error
and an exit.  If someone could please give me any information on how to
get this program to compile I would be very grateful.  Thanks.
