You coud use the emacs function expand-file-name:
  expand-file-name is a built-in function.
  (expand-file-name NAME &optional DEFAULT-DIRECTORY)
  
  Convert filename NAME to absolute, and canonicalize it.
  Second arg DEFAULT-DIRECTORY is directory to start with if NAME is relative
   (does not start with slash); if DEFAULT-DIRECTORY is nil or missing,
  the current buffer's value of default-directory is used.
  File name components that are `.' are removed, and
  so are file name components followed by `..', along with the `..' itself;
  note that these simplifications are done without checking the resulting
  file names in the file system.
  An initial `~/' expands to your home directory.
  An initial `~USER/' expands to USER's home directory.
  See also the function `substitute-in-file-name'.

gnudoit "(ediff (expand-file-name \"%2\" \"%1\") (expand-file-name \"%3\" 
\"%1\"))"

Then you call the batch file with the full directory path (don't know
how to get this) and the two file names.
