 *  It takes a variable number of arguments.
 *  It always allocates a new string for the result, so make sure
 *   to free the return value when finished with it.
 *
 *  The first arg is the number of path segments that follow.
 *  The arguments following count are a list of path segments.
 *  A path segment may be NULL.
 *
 *  Path segments will be added with a \ seperating them.
 *  A \ will not be added after the last segment, however if the
 *    last segment is NULL, then the last character will be a \
