I have a fairly default install of 1.4rc1 at
http://www.wikigaming.com/ that I am getting a syntax error from on IE
6/Win. Specifically it states that there is a syntax error on line
14, char 1 on every page. Looking at the source, I notice that there
are 10 blank lines before the !DOCTYPE tag, and that line 14 is the
first meta tag (Content-Type).
Do you have a lot of blank lines at the start or end of your
LocalSettings.php? Have you edited any other files with the same effect?
