If you want to re-port a newer version of expat
these are the changes WRT release 2.0.1.

	rm -fr configure amiga vms win32 bcb5 conftools tests configure.in expat_config.h.in 
	rm -rf Changes MANIFEST Makefile.in README examples expat.dsw
	rm -rf */*.def */*.dsw  */*.dsp */*.cxx 
	rm -f xmlwf/unixfilemap.c  xmlwf/ct.c xmlwf/xmlmime.c wmlwf/win32filemap.c
	rm -f lib/macconfig.h lib/amigaconfig.h lib/winconfig.h lib/Makefile.MPW

	add README.plan9

	add expat.proto

	add lib/mkfile
	
	add wmlwf/mkfile

	add lib/plan9config.h

	add the following clause to:  xmlparse.c xmlrole.c xmltok.c
		#elif defined(plan9)
			#include "plan9config.h"
			
	modify wmlwf/readfilemap.c to honour HAVE_UNISTD_H, however this only 
	removes compilation warnings and xmlwf is only used as a regression test
	anyway.
