I have a makefile which I want to use for both DOS
(with DJGPP) and Unix.  There's a problem, though -
the 'install' rule needs to use COPY on DOS and cp
on Unix (because I can't guarantee that someone 
compiling the DOS version will have installed the
DJGPP fileutils).

So I have a rule like:

install:
	$(CP) *.exe $DJDIR/bin

and of course in the case when variable CP = COPY it
fails.  What I tried was to use

  $(DJDIR/bin:/=\\)

but any variant of that works only if there are spaces round 
the slash.

I really don't want to have two makefiles...

Even worse, the environment variable DJDIR is set as C:/DJGPP.
I know there was some reason for using slash instead of backslash,
something wouldn't work, but I can't find any mention of this
variable in either the FAQ or in readme.1st.  Is there a use for
this variable, possibly in other install scripts, or is it
a relic from some older installation (DJGPP version 1, possibly)?

Alternatively, is there a standard 'install' program in the DJGPP
distribution?
