Only occurs on Leopard if QTKit < 7.6.3 is installed.

SOFT_LINK_POINTER asserts in a debug build. You might add a SOFT_LINK_POINTER_OPTIONAL version that does not.

Addressed Eric's comment by adding SOFT_LINK_POINTER_OPTIONAL.

We don't actually check the QTKit version here, so it would probably be better to say something like "... see if the current version of QTKit has NoRemoteToLocal ..." instead.

How about: "Check to see if QTSecurityPolicyNoRemoteToLocalSiteAttribute is defined, which was added in QTKit 7.6.3."

I thought it was important to mention that "NoCrossSite" does the right thing in versions of QTKit previous to 7.6.3.

That sounds fine.
