    _______________________________________________________

Details:

If you call make with a variable override X=y it will
not be propagated correctly to other Makefiles:

make TARGET=success
will lead to
make -f Makefile.sub -$(MAKEFLAGS)
being expanded into
make -f Makefile.sub -TARGET=success

but using
make -w TARGET=SUCCESS
will correctly expand to
make -f Makefile.sub -w -- TARGET=SUCCESS

See attached Makefiles as an example
make TARGET=success 
fails badly, whereas
make -w TARGET=success
succeeds. To my understanding
make TARGET=success
should expand "make -f Makefile.sub -$(MAKEFLAGS)" to
make -f Makefile.sub -- TARGET=success

Platform: Linux, Ubuntu 8.04, make -v
GNU Make 3.81
