[xml] configure and LIBXML_UNICODE_ENABLED

["Prashant R" <ramapra gmail com>]

Hi ,

I am trying to configure and build libxml2 on mac OS 

these are my configure options 

/configure --prefix=`pwd`/Output --disable-shared --enable-static

 --with-minimum --with-tree --with-valid  --with-xpath  --with-writer --with-output --with-c14n --with-push 

--without-schemas --without-reader --without-debug --without-docbook --without-xinclude --without-xptr --without-modules --without-iconv --without-legacy  --without-sax1 --without-regexps --without-schematron --without-fexceptions

I see that in xmlversion.h 

LIBXML_UNICODE_ENABLED is set to 0

If i change the options to include schemas --with-schemas

LIBXML_UNICODE_ENABLED is set to 1

is there a way i can control this directly ( i would want to explicity have LIBXML_UNICODE_ENABLED set to 1 )
