I am not sure I completely understood your question, but I think you are
refering to the fact that the foreign_type structures in the compiler
are very related to how we do things on the .NET backend (ie we store
whether something is a reference or value type, where the type is
located and so on).  Am I correct?

I have refactored that code as part of my change to allow C foreign
types, see

http://www.cs.mu.oz.au/research/mercury/mailing-lists/mercury-reviews/mercury-reviews.0203/0045.html

Unfortunately I haven't addressed the review comments on this yet, nor
checked it in.  If this is what you are referring do, would the changes
I made help you?

Peter

PS. In future it is better to ask questions like this on
mercury-developers so that all the Mercury developers can answer you
questions.
