This is actually a useful warning, since -ffunction-sections not only affects debugging but also adds unnecessary size to executables on PE-COFF targets (and others where ld does not support --gc-sections). One way to avoid is to add --enable-cxx-flags='-fno-function-sections -fno-data-sections' to configure Danny
