make_absolute_filename - Makes an absolute filename from a path and relative filename. Allegro game

       Makes an absolute filename from an absolute path and a relative filename, storing at  most  `size'  bytes
       into  the  `dest'  buffer.  This  is  like  calling  replace_filename() and then canonicalize_filename().
       Example:

          char buf[256];
          ...
          make_absolute_filename(buf, "/usr/games/",
                                 "../temp.txt", sizeof(buf));
          /* This would create /usr/temp.txt */

       make_absolute_filename  -  Makes  an  absolute  filename  from a path and relative filename. Allegro game
       programming library.

       Returns a copy of the `dest' parameter.
