+ *@@ winhMyAnchorBlock:
+ *      returns the proper anchor block (HAB)
+ *      for the calling thread.
+ *
+ *      Many Win* functions require an HAB to be
+ *      passed in. While many of them will work
+ *      when passing in NULLHANDLE, some (such as
+ *      WinGetMsg) won't. If you don't know the
+ *      anchor block of the calling thread, use
+ *      this function.
+ *
+ *      This creates a temporary object window to
+ *      find out the anchor block. This is quite
+ *      expensive so only use this if there's no
+ *      other way to find out.
