Hi,
some time ago (Sun, 3 Nov 2002 17:03:25 +0200) I posted an example
that showed strange results with the target specific += operator.
Now I found the time to fix the problem with the attached patch,
i.e. the example
======== Makefile start ===============
.PHONY: targ
targ:
@echo "T=<$T>"
T := 1
targ: T = 2
targ: T += 3
======== Makefile end ===============
gives now the output T=<2 3> instead of T=<1 2 3>.
I hope the patch doesn't break desired behaviour, but after all
the "make check" doesn't report any error.
Best Regards,
Oliver
