Indeed, you are right.  If I start cygwin64 from its installed .bat
file, I get a Cygwin terminal with HOME as /home/moss, under the
C:\cygwin64 Cygwin root.  So it is something about starting using
my (32 bit) .XWinrc.  Presumably the 32-bit HOME is being passed
as an environment variable.  The trick will be to get it unset
so that the 64-bit bash uses its own /home/moss.  I think I'll
have to play with the .XWinrc more to figure that out.
