Think I've managed to get this working.  I hadn't noticed that you can 
use the '-x' flag to tell g++ which language it's compiling.

I added the following lines to darwin.jam:

# ------------------------------------------------------------
# BEGIN Insertion into darwin.jam
# ------------------------------------------------------------

type.register M : m ;

generators.register-c-compiler darwin.compile.m 
  : M : OBJ : <toolset>darwin ;

rule compile.m
  { LANG on $(<) = "-x objective-c" ; }

actions compile.m
  { "$(CONFIG_COMMAND)" $(LANG) $(OPTIONS) $(USER_OPTIONS) -D$(DEFINES)
-I"$(INCLUDES)" -c -o "$(<)" "$(>)" }

# ------------------------------------------------------------
# END Insertion into darwin.jam
# ------------------------------------------------------------

Can anyone tell me if I've done this correctly?

Cheers,
Steve
