If this is at all a problem, then the Makefile could just look for itself 
whether iostream.h (or whatever fails there) is installed, with a command 
like this:

 command.com /c if exist $(patsubst /,\\,${DJDIR})\lang\cxx\iostream.h ..

etc.  Put something instead of the dots, so it will make a difference.  
For example, you could invoke this command with the $(shell) function and 
let it say "echo YES" if the header exists, then test with `ifeq' that 
$(shell) returns YES.  If it doesn't, you could invoke "make nocpp" 
recursively.  Anyway, something along these lines.

I don't believe that telling users to type "make nocpp" will be a
solution, since they will have to read about that in order to know ;-)

(Note: the "command.com /c" thing is deliberate, so this works even if 
$(SHELL) points to Bash or some such.)
