I believe the patch does not have the desired effect, because make(1) always sets CC automatically: $ cat raj.mk CROSS_COMPILE=x86_64-linux-gnu- CC?=$(CROSS_COMPILE)gcc .PHONY: default default: @echo CC=$(CC) $ make -f raj.mk CC=cc With your patch, those who specify CROSS_COMPILE, or for whom gcc and cc are different, will get different (worse) behavior. I believe this idea has been discussed before, but it is hard to search for because few search engines will let you search on "CC ?=" and not just ignore the "?=". Also I am not sure why you are submitting this patch on -rt-users, it doesn't seem to be particularly relevant to the RT patchset.
