How can I help?  By the way, I took the liberty of forwarding on the
original e-mail from Rhys to the ECMA TC39 TG3 committee.

That's not how I read this thread.  There is a desire to be able to code a
single C# source that will work portably across CLI implementations with 32
and 64 bit platforms.  My example was to call "system".

Because the proposal will do "upgrade" conversions when necessary, input
parameters to C will work fine.  What remains is output parameters, which
(except for unsafe code and references) essentially reduces to a single
case: output parameters.
