* Makefile (MAKE_VERSION): 20130730
Merge with NetBSD make, pick up
o Allow suppression of --- job -- tokens by setting
.MAKE.JOB.PREFIX empty.
2013-07-16 Simon J. Gerraty <sjg@bad.crufty.net>
* Makefile (MAKE_VERSION): 20130716
Merge with NetBSD make, pick up
o number of gmake compatability tweaks
-w for gmake style entering/leaving messages
if .MAKE.LEVEL > 0 indicate it in progname "make[1]" etc.
handle MAKEFLAGS containing only letters.
o when overriding a GLOBAL variable on the command line,
delete it from GLOBAL context so -V doesn't show the wrong
value.
2013-07-06 Simon J. Gerraty <sjg@bad.crufty.net>
* configure.in: We don't need MAKE_LEVEL_SAFE anymore.
* Makefile (MAKE_VERSION): 20130706
Merge with NetBSD make, pick up
o Shell_Init(): export shellErrFlag if commandShell hasErrCtl is
true so that CompatRunCommand() can use it, to ensure
consistent behavior with jobs mode.
o use MAKE_LEVEL_ENV to define the variable to propagate
.MAKE.LEVEL - currently set to MAKELEVEL (same as gmake).
o meta.c: use .MAKE.META.IGNORE_PATHS to allow customization of
paths to ignore.
