Can we just disable those stuff by default if we put --disable-hosted-libst= dcxx here? it will disable all languages besides c, c++. libgcc will be built with -ffreestanding. quadmath, ssp whatever would get disabled. and --without-headers and --with-newlib should work here? And cstdint header file does not work either since it fails to detect stdin= t.h for configure at build time. Although manually remove the __HAVE_STDINT_H__ macro and include stdint.h w= ould work.=
