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)
