Install fails if subdirectory is used

[ringmaster]

The $guessurl variable set in install.php is used to set the main blog directory during the install. It is formed from the $REQUEST_URI, which presumably is the request_uri of the install page, but it seems this variable is never set (fyi-XP IIS). It's a coincidence that it works when installing to the root.

If you install WordPress to a subdirectory, all sorts of bad things happen, the first two being that the admin login form can't reference the correct CSS file and then on submission redirects to a non-existant page.

The previous bugnote doesn't seem to be the same issue, but could be among a group of many problems that Windows hosts would encounter.

A documented list of requirements/*good* instructions for installing on Windows servers might be helpful.

REQUEST_URI is no longer used in install.
