+ * Function    :  make_path
+ *
+ * Description :  Takes a directory name and a file name, returns 
+ *                the complete path.  Handles windows/unix differences.
+ *                If the file name is already an absolute path, or if
+ *                the directory name is NULL or empty, it returns 
+ *                the filename. 
+ *
+ * Parameters  :
+ *          1  :  dir: Name of directory or NULL for none.
+ *          2  :  file: Name of file.  Should not be NULL or empty.
+ *
+ * Returns     :  "dir/file" (Or on windows, "dir\file").
+ *                It allocates the string on the heap.  Caller frees.
+ *                Returns NULL in error (i.e. NULL file or out of
+ *                memory)
