   The same cvs2cl from CVS HEAD.

   I would like to execute it with full output path, e.g.

   "perl cvs2cl.pl --file D:\MyProjects\Project1\reports\ChangeLog"

   when output is not distributed, everything is groupped in directory
   "./" and finally script is trying to create file with the path
   ./D:\MyProjects\Project1\reports\ChangeLog/cvs2clXXXX.tmp" and
   fails.  Looks like the code is fixing this issue only for unixes
   where full path is started with '/' however on windows full path
   starts with drive and the fix is not working.
