// ATL's implementation of Release always returns 0 unless _DEBUG is

// circumstances.  I don't want to define _DEBUG because it brings in a
// whole lot of baggage from MMC that I don't want to deal with, but I do
// want to avoid this assertion in OLE, so on debug builds, I'll go ahead
// and define _DEBUG for the appropriate ATL header file but I'll undefine
// it again right afterward.  This is a little flakey but it is relatively
// safe and it achieves the desired goal.
