Kai, what's your opinion? I suspect you missed my posing to l-k http://www.uwsg.indiana.edu/hypermail/linux/kernel/0301.3/1203.html

..... There is also one change I have made on the buildsystem. Because I'm using some perl inline scripts in the $cmd_xxx the >'< and >$< signs in the inline perl scripts cause trouble (perl -e '...$x=....'), the >'< because of the echo command, the >$< when rereading from the xxx..cmd files. Could this be applied to the original file?
scripts/Makefile.lib: +-------------------------------+
# =========================================================================== # Generic stuff # ===========================================================================
# function to only execute the passed command if necessary # the ' -> '\'' and $ to $$ substitution are done if $(cmd_$(1)) includes a inline perlscript
if_changed = $(if $(strip $? \ $(filter-out $(cmd_$(1)),$(cmd_$@))\ $(filter-out $(cmd_$@),$(cmd_$(1)))),\ @set -e; \ $(if $($(quiet)cmd_$(1)),echo ' $(subst ','\'',$($(quiet)cmd_$(1)))';) \ $(cmd_$(1)); \ echo 'cmd_$@ := $(subst $$,$$$$,$(subst ','\'',$(cmd_$(1))))' > $(@D)/.$(@F).cmd)
