Please use IS_DIR_SEPARATOR instead of testing for '/' literally.  And
the second part of the if clause cannot happen at all, so it should be
removed.

Also, the GNU coding standards say to put the braces like this:

   if (something)
    {
      do_something;
      do_something_else;
    }

> Â Â  Â  else fullname = concat (dirname, SLASH_STRING, filename, (char *)NULL);

Make "else" have its own line, like this:

   else
     fullname = concat (dirname, SLASH_STRING, filename, NULL);
