         svn merge of revisions with many conflicts in CHANGES, generated html and some changes that do not belong

         The win build system changes are excluded at the moment, as I was unable to merge the

         changes via svn. Probably the 2.4.x is hand-edited so it does not allow that. The necessary

         windows changes are best made to the new branch and then, once working satisfactory, merged

         over.

         Resetting the votes.

     +1: icing

     -1: steffenal: OS signals error at httpd start, win build not complete. Details see post dev list

  *) mod_md: backport of mod_ssl changes to get interworking ACME support. Needs mod_md backport propoals above to find mod_md.h include file with otional functions.
