// 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.
