Hi, the documentation for implicit rules says for compiling C/C++ $(CC) $(CPPFLAGS) $(CFLAGS) -c $(CXX) $(CPPFLAGS) $(CXXFLAGS) -c
but the source says default.c:479: "COMPILE.c", "$(CC) $(CFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c", default.c:483: "COMPILE.cc", "$(CXX) $(CXXFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c", the attached patch fixes the documentation for these two rules. also $(CPPFLAGS) and $(CFLAGS) are swapped (should not be an issue in most cases). I think there are more rules that use $(TARGET_ARCH) without being mentioned in the docs. Regards, Dominik
