moved to libxml directory - this allow simplify automake/autoconf. Now
Thu Feb 23 02:03:56 CET 2001 Tomasz Kłoczko <kloczek@pld.org.pl> * *.c *.h libxml files: moved to libxml directory - this allow simplify automake/autoconf. Now isn't neccessary hack on am/ac level for make and remove libxml symlink (modified for this also configure.in and main Makefile.am). Now automake abilities are used in best way (like in many other projects with libraries). * include/win32config.h: moved to libxml directory (now include directory isn't neccessary). * Makefile.am, examples/Makefile.am, libxml/Makefile.am: added empty DEFS and in INCLUDES rest only -I$(top_builddir) - this allow minimize parameters count passed to libtool script (now compilation is also slyghtly more quiet). * configure.in: simplifies libzdetestion - prepare separated variables for keep libz name and path to libz header files isn't realy neccessary (if someone have libz installed in non standard prefix path to header files ald library can be passed as: $ CFALGS="-I</libz.h/path>" LDFLAGS="-L</libz/path>" ./configure * autogen.sh: check now for libxml/entities.h. After above building libxml pass correctly and also pass "make install DESTDIR=</install/prefix>" from tar ball generated by "make dist". Seems ac/am reorganization is finished. This changes not touches any other things on *.{c,h} files level.
