I'm referring to the the fact that the issue has to be address explicitly at
all. This is a side effect of implementation of the export functionality.
I'm hoping that re-implementing th export functionality (keeping the
interface, macros, etc) will make ADL and two phase lookup function as one
would expect without having to address it. At that point I would just remove
this information from the documentation.

Other posts on this list have raised questions about VC 7.1 issue regarding
ADL. note that VC 7.1 doesn't support two-phase lookup so confuses the
issue significantly - at least for me. Again, I'm hoping I can make this
all go away with a different implementation of export. - though I don't know
for sure yet.

I would hope that changes from 1.31 to 1.32 would be very minimal if any.
