MAKEFLAGS

[Sebastiano Mauri]

Hi,
I can't understand the following behaviour:

> cat Makefile
#-----------------------------------------------------------------------------------
list_flag  = $(subst =flag,,$(filter %=flag,$(MAKEFLAGS)))
#
.PHONY: default info
#
default: info b
#
info:
        @echo 'MAKEFLAGS=|$(MAKEFLAGS)|'
        @echo 'list_flag=|$(list_flag)|'
        @echo 'origin MAKEFLAGS=$(origin MAKEFLAGS)'
#
define testFunc
$(1):
        @echo '----------------- rule testFunc'
        @echo 'target=$$@'
endef
#
$(foreach el,$(list_flag),$(eval $(call testFunc,$(el))))
#-----------------------------------------------------------------------------------

> make d=flag c=tmp b=flag a=tmp
MAKEFLAGS=|a=tmp b=flag c=tmp d=flag|
list_flag=|b d|
origin MAKEFLAGS=file
make: *** No rule to make target `b', needed by `default'.  Stop.


if however I  add 'MAKEFLAGS  = d=flag c=tmp b=flag a=tmp' in the Makefile

> make d=flag c=tmp b=flag a=tmp
MAKEFLAGS=|a=tmp b=flag c=tmp d=flag|
list_flag=|b d|
origin MAKEFLAGS=file
----------------- rule testFunc
target=b

and with 'MAKEFLAGS  = a=tmp b=tmp c=tmp d=tmp'

> make d=flag c=tmp b=flag a=tmp
MAKEFLAGS=|a=tmp b=flag c=tmp d=flag|
list_flag=|b d|
origin MAKEFLAGS=file
make: *** No rule to make target `b', needed by `default'.  Stop.

I'am running GNU Make 3.80 with patch 'eval-crash.diff' on Linux 
2.4.21-4.EL.

Thanks  for any help
Regards,
Sebastiano
