Returns a boolean as to whether or not warnings are enabled for the warning
category C<w>.  If the category is by default enabled even if not within the
scope of S<C<use warnings>>, instead use the L</ckWARN_d> macro.

=for apidoc Am|bool|ckWARN_d|U32 w

Like C<L</ckWARN>>, but for use if and only if the warning category is by
default enabled even if not within the scope of S<C<use warnings>>.

=for apidoc Am|bool|ckWARN2|U32 w1|U32 w2

Like C<L</ckWARN>>, but takes two warnings categories as input, and returns
TRUE if either is enabled.  If either category is by default enabled even if
not within the scope of S<C<use warnings>>, instead use the L</ckWARN2_d>
macro.  The categories must be completely independent, one may not be
subclassed from the other.

Like C<L</ckWARN2>>, but takes three warnings categories as input, and returns
TRUE if any is enabled.  If any of the categories is by default enabled even
if not within the scope of S<C<use warnings>>, instead use the L</ckWARN3_d>
macro.  The categories must be completely independent, one may not be
subclassed from any other.

TRUE if any is enabled.  If any of the categories is by default enabled even
if not within the scope of S<C<use warnings>>, instead use the L</ckWARN4_d>
