Not at all, but the registry fiddling may not be advisable to
mention, and I'd prefer to be more definite about the effect of
explicitly setting TZ, but I didn't have time to look into the
"posixrules" stuff.  [Cygwin has a small file called, if I remember
correctly, posixrules.c, which consists of the precompiled TZ data
recorded as a hex vector.  I've no idea how it's used or if it's
up to date.  Is this documented anywhere - does cgf or Corinna
possibly know?]
