Relevant BUGIDs:
Purpose of commit: cleanup Commit summary: --------------- 2008-08-01 Thorsten Kukuk <kukuk@thkukuk.de> * acincludde.m4: Rename to ... * m4/jh_path_xml_catalog.m4: ... this. * m4/*.m4: Remove all autoconf m4 files. Remove old autoconf m4 files from CVS, autogen.sh will now copy current versions from the system. (Avoid having old buggy versions forever).
