It can NOT have a smaller range.  apr_int64_t is a contract that there
are 64 available bits.  If it had 72 bits that wouldn't be the end of
the world.  Is long double or some other type on the watcom compiler
available?

A fullpath is the absolute path (truename is the canonical form that must
be in the proper case).

A root is something you must not ../ up and around.  So it seems to me that
your root is "//node-ID/".  But obviously on this OS, the local node is the
equivilant of "/".  If you want to use the short node ID on the local paths,
that's fine (those roots are "/").  It's important that the paths are
**consistent**!!!  That will allow folks who test filenames for security
purposes are comparing apples to apples.  If they pass the "//local-ID/foo"
path, they better get back "/foo".
