Something really strange is happening. There seems to be some random
variation in the results. For this Makefile:
----------------------------------------------------------------------
FOO:=$(shell echo foo)
BAR:=$(shell ls Makefile)
all:
@echo FOO = $(FOO)
@echo BAR = $(BAR)
----------------------------------------------------------------------
version 3.79.1 always gives:
----------------------------------------------------------------------
FOO = foo
BAR = Makefile
----------------------------------------------------------------------
regardless of the shell. But for 3.80, I see behaviour like this:
----------------------------------------------------------------------
[matt@delta]date; for shell in bash ksh sh; do echo; echo /bin/$shell; make
SHELL=/bin/$shell; done;
Thu Dec 19 16:19:27 GMT 2002
/bin/bash
FOO =
BAR =
/bin/ksh
FOO =
BAR =
/bin/sh
FOO = foo
BAR =
[matt@delta]date; for shell in bash ksh sh; do echo; echo /bin/$shell; make
SHELL=/bin/$shell; done;
Thu Dec 19 16:19:29 GMT 2002
/bin/bash
FOO = foo
BAR = Makefile
/bin/ksh
FOO = foo
BAR =
/bin/sh
FOO =
BAR =
[matt@delta]date; for shell in bash ksh sh; do echo; echo /bin/$shell; make
SHELL=/bin/$shell; done;
Thu Dec 19 16:19:30 GMT 2002
/bin/bash
FOO =
BAR = Makefile
/bin/ksh
FOO = foo
BAR =
/bin/sh
FOO = foo
BAR =
----------------------------------------------------------------------
I ran some tests with the -d flag, and here is a sample sdiff output
for one job with bash and one with ksh (with the PIDs factored out):
