=head1 Warning and Dieing
In all these calls, the C<U32 wI<n>> parameters are warning category
constants. You can see the ones currently available in
L<warnings/Category Hierarchy>, just capitalize all letters in the names
and prefix them by C<WARN_>. So, for example, the category C<void> used in a
perl program becomes C<WARN_VOID> when used in XS code and passed to one of
the calls below.
=for apidoc Am|bool|ckWARN|U32 w
=for apidoc_item ||ckWARN2|U32 w1|U32 w2
=for apidoc_item ||ckWARN3|U32 w1|U32 w2|U32 w3
=for apidoc_item ||ckWARN4|U32 w1|U32 w2|U32 w3|U32 w4
These return a boolean as to whether or not warnings are enabled for any of
the warning category(ies) parameters: C<w>, C<w1>, ....
Should any of the categories by default be enabled even if not within the
scope of S<C<use warnings>>, instead use the C<L</ckWARN_d>> macros.
The categories must be completely independent, one may not be subclassed from
the other.
=for apidoc Am|bool|ckWARN_d|U32 w
=for apidoc_item ||ckWARN2_d|U32 w1|U32 w2
=for apidoc_item ||ckWARN3_d|U32 w1|U32 w2|U32 w3
=for apidoc_item ||ckWARN4_d|U32 w1|U32 w2|U32 w3|U32 w4
Like C<L</ckWARN>>, but for use if and only if the warning category(ies) is by
default enabled even if not within the scope of S<C<use warnings>>.
=for apidoc Am|U32|packWARN|U32 w1
=for apidoc_item ||packWARN2|U32 w1|U32 w2

=for apidoc_item ||packWARN4|U32 w1|U32 w2|U32 w3|U32 w4
These macros are used to pack warning categories into a single U32 to pass to
macros and functions that take a warning category parameter. The number of
categories to pack is given by the name, with a corresponding number of
category parameters passed.
