Yepp, looks like Jiri's testing/breakage is confirmed; So enhance: tools/perf/Makefile.config: CFLAGS += -Wno-compound-token-split-by-macro tools/build/feature/Makefile: FLAGS_PERL_EMBED += -Wno-compound-token-split-by-macro ...with ?: -Wno-unused-command-line-argument ( -Wno-ignored-optimization-argument ) ...or use "call cc-option" ? Looks like tools/ build ECO system allows this: $ git grep 'call cc-option' tools/ tools/build/Build.include:# Usage: cflags-y += $(call cc-option,-march=winchip-c6,-march=i586) tools/thermal/tmon/Makefile:override CFLAGS+= $(call cc-option,-O3,-O1) ${WARNFLAGS} tools/thermal/tmon/Makefile:override CFLAGS+= $(call cc-option,-fstack-protector-strong) Thanks. - sed@ - > > > >
