Subject: Use buildconf script from trunk, works fine. Changes: - fixed
 indentation - Correct and add a few comments - Remove "$verbose" from libtool
 1 call   (it doesn't implement it) - Reduce code duplication - Remove "force"
 form libtoolize in order to   not overwrite config.(guess|sub).   All
 possibly conflicting old files get removed   by buildconf before calling
 libtoolize.
