Hi, all,  I apologize for the poor state of these minutes.  I was trying
really hard to understand the possible solutions we have to consider, and
got to focusing on that rather than the minutes.

Today's discussion started with Randy's proposal.  The wording he sent out
does not specifically indicate that it would remove $root, but in thinking
about it Randy could not see a clean way except to eliminate $root.

Karen asked a lot of questions trying to understand why we would need to 
eliminate $root.  In the end, it didn't seem that there was a specific
testcase that was an issue, but rather an intuition that it would be 
very difficult not to eliminate it.

There seemed to be three proposals that emerged from the discussion:

1.  The namespaces proposal plus the elimination of $root
2.  Namespaces plus $roots that were only visible to
    a compilation unit, be it a file or set of files.  Only namespaces
    would be allowed to export symbols from a compilation unit.
3.  Using Extern declarations as specified by Peter's proposals.

Karen volunteered to write up a proposal reflecting number 2 to see what 
issues arose in having $root continue to exist.

Because SV-BC meetings will resume at 9am on Monday mornings, our next 
meeting to discuss separate compilation support is scheduled for 9am
Pacific on Tuesday 7/15.
