You can't change this constant without breaking binary compatibility.
In addition, you're increasing the size of the http_t structure to
something like 64k... :)

What you'll need to do is add a char * to the *end* of the http_t
structure and update httpGetField() and httpSetField() to handle
HTTP_FIELD_WWW_AUTHENTICATE values specially, copying as much as
possible to the old field for backwards-compatibility...
