Using make -p, I see these builtin productions: COMPILE.cc = $(CXX) $(CXXFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c COMPILE.cpp = $(COMPILE.cc) COMPILE.c = $(CC) $(CFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c So it seems to me if you distangle your C, C++ and common C/C++ warning flags into three separate categories, and add them to make like: CFLAGS += $(WARN_C) $(WARN_C_CXX) CXXFLAGS += $(WARN_CXX) $(WARN_C_CXX) You'd be all set.
