* Makefile.am catalog.c xmlcatalog.c include/libxml/catalog.h: more work on the XML catalog support. * parser.c include/libxml/parser.h: small cleanup seems using list as a public parameter name can give portability troubles * trionan.c trionan.h xpath.c include/libxml/trionan.h include/libxml/xpath.h include/libxml/Makefile.am: removed trionan from the libxml API, added xmlXPathIsInf and xmlXPathIsNaN wrappers Daniel
