   Wow!! hold the phone.. you are writing a dependent rule for file "ram"
that depends on precompiled_include on your disk?   No wonder it never works.
Best thing I can suggest is to write an execute file that copies it up
there if it is needed -- and always execute it.  slow and sloppy, but you
may win over the whole compile.
    Hmm.. how about:

pgm: $(OBJS)
	execute copypretoram
	ln ...


   Then in the execute script file, do something like this:

if (not exists ram:precompiled_include) then
   copy df0:precompiled_include ram:
endif


   This is the best I can do without Manx make in front of me -- you might
also be able to put ()'s or quotes arround the ram: file name so the ":"
dosen't interfere with make.. something like:

pgm: $(OBJS) (ram:pre_inc)
	ln ...

(ram:pre_inc): pre_inc
	copy rep_inc ram:



>So why didn't make work right?

   because your makefile dosen't check a file in ram, it it copies the file
up there to make a file called "ram" up to date... which is never up to date
since it dosen't exist.

>Or is there something funny about RAM:?

   a ":" is a ":" to make.. I'll bet it can't tell a ":" for a device mane from
one for a rule.
