bug#7603: 24.0.50; compilation of NS variant fails with too old libxml2

[Peter Dyballa]

Hello!

Compilation failed with:

	xml.c: In function ‘parse_region’:
	xml.c:107: error: ‘HTML_PARSE_RECOVER’ undeclared (first use in this  
function)
	xml.c:107: error: (Each undeclared identifier is reported only once
	xml.c:107: error: for each function it appears in.)

LIBXML_DOTTED_VERSION "2.6.16" does not have this enumeration from  
"2.6.32":

	# 178 "/sw/include/libxml2/libxml/HTMLparser.h"
	typedef enum {
	    HTML_PARSE_RECOVER = 1<<0,
	    HTML_PARSE_NOERROR = 1<<5,
	    HTML_PARSE_NOWARNING= 1<<6,
	    HTML_PARSE_PEDANTIC = 1<<7,
	    HTML_PARSE_NOBLANKS = 1<<8,
	    HTML_PARSE_NONET = 1<<11,
	    HTML_PARSE_COMPACT = 1<<16
	} htmlParserOption;

Maybe it's worth to make configure check the version of libxml2...

This old software is part of Mac OS X 10.5.8.

Theory and practice are the same, in theory, but, in practice, they  
are different.

Hello!

Looking into the configure and config.log files and experimenting with  
pkg-config it seems that configure checks for the wrong version  
number. Instead of 2.2.0 (maybe a years old version number) a larger  
value/more recent version number should be checked, obviously greater  
than 2.6.16 to satisfy the dependency from

	typedef enum {
	    HTML_PARSE_RECOVER = 1<<0,
	    HTML_PARSE_NOERROR = 1<<5,
	    HTML_PARSE_NOWARNING= 1<<6,
	    HTML_PARSE_PEDANTIC = 1<<7,
	    HTML_PARSE_NOBLANKS = 1<<8,
	    HTML_PARSE_NONET = 1<<11,
	    HTML_PARSE_COMPACT = 1<<16
	} htmlParserOption;

in .../include/libxml2/libxml/HTMLparser.h.

Looks reasonable.  Committed; thanks.
