[krbdev.mit.edu #5859] Build of windows/identity fails in clean directory

[Jeffrey Altman via RT]

Sorry, I was thinking of hhc.exe which comes from the HTML Help Workshop.

hcw.exe is deprecated because the .HLP format is no longer supported by
Microsoft.  .chm (HTML Help) is the only supported Help file format.  
hcw is only used to build the leash32.hlp file which is to the best of
my knowledge no longer being built for KFW.

There was agreement that leash32.exe and associated files would be
removed from all installations after 3.2.2

There is an open ticket for doing so.
