The patents in question are based on unification points-to analysis held 
by Microsoft.  Working around them is easy, just don't use those 
techniques.  Unfortunately, DSA is designed and built around them, so it 
can't be "simply modified" to not use them.

Also, as far as software patents go, they are fairly reasonable.  I don't 
think there was any prior art in that area.
