  include/libxml/xmlerror.h include/libxml/xmlexports.h
  include/libxml/xmlschemas.h: applied a patch from Marcus Boerger
  to fix problems with calling conventions on Windows this should
  fix #309757
Daniel

* regressions.py, regressions.xml: new files for running
  regression tests under Python.  Not yet complete, but
  should provide good testing under both Linux and Windows.
* testHTML.c, testSAX.c, xmllint.c: changed the 'fopen' used
  for --push testing to include the 'rb' param when compiled
  under Windows.

* debugXML.c testHTML.c tree.c doc/examples/*.c
  include/libxml/xmlsave.h: fixing compilation bug with some options
  disabled as well as --with-minimum should fix #134695
Daniel

* testHTML.c: another small patch from Mark Vadoc
Daniel

* genChRanges.py, chvalid.c, include/libxml/chvalid.h,
  include/libxml/parserInternals.h: enhanced macros to avoid
  breaking ABI from previous versions.
* catalog.c, parser.c, tree.c: modified to use IS_* macros
  defined in parserInternals.h.  Makes maintenance much easier.
* testHTML.c, testSAX.c, python/libxml.c: minor fixes to avoid
  compilation warnings
* configuration.in: fixed pushHTML test error; enhanced for
  better devel (me) testing

* HTMLparser.c Makefile.am configure.in legacy.c parser.c
  parserInternals.c testHTML.c xmllint.c include/libxml/HTMLparser.h
  include/libxml/parser.h include/libxml/parserInternals.h
  include/libxml/xmlversion.h.in: added a new configure
  option --with-push, some cleanups, chased code size anomalies.
  Now a library configured --with-minimum is around 150KB,
  sounds good enough.

  Okay this is scary but it is just adding a configure option
  to disable output, this touches most of the files.
Daniel

* HTMLparser.c testHTML.c xmllint.c include/libxml/HTMLparser.h:
  added the same htmlRead APIs than their XML counterparts
* include/libxml/parser.h: new parser options, not yet implemented,
  added an options field to the context.
* tree.c: patch from Shaun McCance to fix bug #123238 when ]]>
  is found within a cdata section.
* result/noent/cdata2 result/cdata2 result/cdata2.rdr
  result/cdata2.sax test/cdata2: add one more cdata test
