Description:
------------
If there is a newline befor the XML-declaration, the parser fails.
The w3.org only demand:
"The document type declaration MUST appear before the first element in the document."

Test script:
---------------
<?php

$data = '<?xml version="1.0"?><foo>bar</foo>';

function test($data) {
    print "try to parse: '" . htmlentities($data) . "'<br>\n";
    $parser = xml_parser_create();
    if (!xml_parse($parser, $data)) {
        print "Error: " . xml_error_string(xml_get_error_code($parser)) . "<br>";
        print "Error in Line " . xml_get_current_line_number($parser) . " Column " . xml_get_current_column_number($parser) . "<hr>\n";
    } else {
        print "works fine<hr>";
    }
}
test($data);
test("\n" . $data);


Expected result:
----------------
I expect, that both test succeed.

Actual result:
--------------
Only the first test succeed, the second fails in Line 1 Column 21 "Reserved XML Name".
