Hi Hartmut,
there is an annoying bug in 6-STABLE make(1), where -f - seems to
serialize the target making.
Consider the following Makefile
all: a b c d
a b c d:
@echo Makeing ${.TARGET}
@sleep 4
And observe the following behaviour:
$ make -j4
Makeing a
Makeing b
Makeing c
Makeing d
<pause>
$ make -j4 -f- < Makefile
Makeing b
Makeing d
<pause>
Makeing a
<pause>
Makeing c
<pause>
$
The make(1) on -CURRENT has this fixed already, is there any chance of
this getting MFCed?
AFAICS the following revisions are not up to date (wrt to CURRENT):
