Subject: Question regarding rb_include_module

Hi all,

Ruby 1.8.1
Windows 2000

For the next release of win32-process, I'm getting rid of the toplevel
Win32 module/namespace.  Thus, you can do "Process.fork" instead of
"Win32::Process.fork".  However, I would like to be able to just do
"fork" (no 'Process') in the same manner that you can on *nix.  In
pure Ruby I would do something like this:

module Process
   def fork
      puts "fork!"
   end
end

class Object
   include Process
end

fork # -> "fork!"

I can't get this to work on the C side, however.  I tried this at the
end of "Init_process()":

rb_include_module(rb_cObject,rb_mProcess);

But, it didn't seem to work.  What am I not seeing?

Regards,

Dan
