Currently it seems to be too late because freeing fails sometimes.
Perhaps something else has taken care of resources before the attempt
of freeing them is being made by calling `w32_free_menu_strings'.

An interesting detail might be that only menu entries displayed in
bold may become garbled.  These entries don't have an associated
action.

Ugh, given the time I currently have for coding this is likely beyond
me.
