After upgrade of debian package libtool (1.5.26 to 2.2.26a), there are
serious make problems.

To solve these problems i need the following 3 steps to do. I'm not sure
which files are updated by these steps.

sh> make distclean

sh> libtoolize
libtoolize: putting auxiliary files in `.'.
libtoolize: linking file `./ltmain.sh'

libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.in and
libtoolize: rerunning libtoolize, to keep the
correct libtool macros in-tree. libtoolize:
Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am.


sh> autoreconf


Now ./confugure && make && etc.
