I wasn't aware of the hackery Mark does at the end of the script - use a
frozen exe, pretend it is a frozen dll, to trick win32com.server.register
into registering it as dll server.

>From what I have found in the code, setting pythoncom.frozen = True
seems to be safe.  It would be interesting to know the values of
sys.frozen and pythoncom.frozen (if any) before.

I wanted to make a bugfix release of py2exe - although this fixes
different bugs (I assume).  If there's a problem with COM registration I
would like to wait until this is resolved.
