sys-include/newlib.h

Hi Jeff,

No, as stdio.h needs to exist there ($target_header_dir gets set to --with_headers value)

if { { test x$host != x$target && test "x$with_sysroot" = x ; } ||
       test x$with_newlib = xyes ; } &&
     { test "x$with_headers" = xno || test ! -f "$target_header_dir/stdio.h"; } ; then
       inhibit_libc=true

And creating a dummy stdio.h doesn't work, as that then gets installed in sys-include and used.

For a clean build, these only exist after newlib is built and installed though. Does that mean GCC needs to be built twice?

Thanks,
Jon
