What I ususally do if it happens in one or two files only (of 3rd party code that I have) is add something like foo.o: CFLAGS += -Wno-error=unused-but-set-variable or foo.o: CFLAGS += -Wno-unused-but-set-variable This does not switch -Werror globally or anything of the kind. I am fairly sure that this can be done in the kernel in a similar manner. -- Oleg Goldshmidt | o...@goldshmidt.org
