parts of the configuration process on each invocation. Instead of relying on a stamp file, we now compare version numbers of generated files with the ChangeLog timestamp manually in the affected make rules to decide whether regenerating is necessary: * Makefile.am (EXTRA_DIST): Remove stamp-vcl. (clean-ltmain-sh): Also remove users' obsolescent stamp-vcl. (rebuild): Keep some common code here for... (libtool, libltdl/m4/ltversion.m4, libltdl/config/ltmain.sh): Rewritten to work without reference to intermediate stamp-vcl file. * configure.ac (CONFIG_STATUS_DEPENDENCIES): Change from stamp-vcl to ChangeLog. * NEWS: Removed entry saying this fix is needed.
