All library-internal declarations made in a library-private header
file (such as libsvn_wc/wc.h) must be signified by two underscores
after the library prefix (such as svn_wc__ensure_directory). All
declarations private to a single file (such as the static function
get_entry_url inside of libsvn_wc/update_editor.c) do not require any
additional namespace decorations.

So proper name for dirent_t in FSX is svn_fs_x__dirent_t.
