> The file:
>    src/native/src/org_apache_hadoop.h
> declares the static function "do_dlsym" in the header as non-inline. Files including the header (e.g. for the THROW macro) receive a "defined but unused" warning during compilation.
> This function should either a) be inlined or b) use GCC "unused" attribute.
