I don't know if that is a feature of libtool or not. libtool won't use them, but that isn't how it works. When the top level Makefile builds target-libstdc++-v3, it passes CFLAGS=$(CFLAGS_FOR_TARGET). You do have to run make at the top level, always. (Although, if you set CFLAGS_FOR_TARGET when you run configure, then I believe that that will become the default CFLAGS for the target libraries). This may not apply to the Android libc--it depends on how the configury/make was set up. It should work for libstdc++-v3. I've used it. Ian
