Hi,

I just downloaded beta 18 and found what I consider a major bug in make.
Here is a sample Makefile:

---start Makefile---
..SILENT:
SHELL =		/bin/sh

FRED =		fred
MARY =		mary
LIST =		file1 file2 file3 file4
LIST_C =	${LIST:=.c}

level1:
	echo ; \
	echo $@ ; \
	MIKE=mike ; export MIKE ; \
	echo FRED = $(FRED) ; \
	echo MARY = $(MARY) ; \
	echo MIKE = $$MIKE ; \
	echo LIST = $(LIST) ; \
	echo LIST_C = $(LIST_C) ; \
	echo OPTION = $(OPTION) ; \
	$(MAKE) level2

level2:
	echo ; \
	echo $@ ; \
	echo FRED = $(FRED) ; \
	echo MARY = $(MARY) ; \
	echo MIKE = $(MIKE) ; \
	echo LIST = $(LIST) ; \
	echo LIST_C = $(LIST_C) ; \
	echo OPTION = $(OPTION)
---end Makefile---

Now here is the bad output:

level1
FRED = fred
MARY = mary
MIKE = mike
LIST = file1 file2 file3 file4
LIST_C = file1.c file2.c file3.c file4.c
OPTION = option

level2
FRED = fred
MARY = mary
MIKE = mike
LIST = file1 file2 file3 file4
LIST_C = file1.c file2.c file3.c file4.c
OPTION =

Now here is what the output should be:

level1
FRED = fred
MARY = mary
MIKE = mike
LIST = file1 file2 file3 file4
LIST_C = file1.c file2.c file3.c file4.c
OPTION = option

level2
FRED = fred
MARY = mary
MIKE = mike
LIST = file1 file2 file3 file4
LIST_C = file1.c file2.c file3.c file4.c
OPTION = option  <- THIS IS DIFFERENT

Note that OPTION is not being "exported" to the next instance of make.

Does anyone know if build 19 fixes this?
