I know that unsetenv() can be changed without problems since it has no
return value at the moment.  The others are more difficult but not
impossible.  I see that a mild discussion has occurred on cvs.  :)

Here are both scenarios with my code changes:
BSD[1] (only unsetenv() is updated to return an int.  Easy to change
         back)
POSIX[2] (all *env() functions are updated to reflect POSIX)
