As far as I can see the only kernel header that gen_facilities.c is actually interested in is autoconf.h. (autoconf.h will be included via in kconfig.h.) So it seems the odd $(LINUXINCLUDE) variable in that Makefile could be replaced with something like: -include $(srctree)/include/generated/autoconf.h Paul Bolle
