Peter, Nickolay,

./configure --with-libxml does not accept a location argument.  This 
makes it impossible to configure 8.3 with LibXML on the Mac, because I 
can't upgrade the main libxml without breaking something, and 
./configure doesn't let me specify an alternate location.

--with-libxml should accept a library location.
