Are you sure that it actually worked in Pike 7.6 (ie that zero_type(NULL)
was 1)?

The reason that it fails is probably that NULL actually gets the value
UNDEFINED (and not 0) in Pike 7.8. Note that symbols with the value
UNDEFINED in modules indicate that the symbol doesn't exist, thus the
error message.
