# Since the targets '.1.2', '.1.3' and '.1.4' have now been turned into

# At this point, 'next-main' is still the default main target, even though
# it is not the first regular target anymore.

# Define and undefine the suffixes, changing their order.
# XXX: This should have no effect, but as of 2020-11-22, it does.
# For some reason, mentioning the suffixes in reverse order disables them.
