         Determines if the path specified by a given String is

         an absolute path or not. On UNIX systems, a pathname is absolute

         if its prefix is "/". On Win32 systems, a pathname is absolute

         if its prefix is a drive specifier followed by "\\", or if its

         prefix is "\\".
