+The XSUB-writer's equivalent to Perl's C<wantarray>. Returns C<G_VOID>,
+C<G_SCALAR> or C<G_ARRAY> for void, scalar or array context,
+respectively.

+=for apidoc Amn|U32|GIMME
+A backward-compatible version of C<GIMME_V> which can only return
+C<G_SCALAR> or C<G_ARRAY>; in a void context, it returns C<G_SCALAR>.
+Deprecated. Use C<GIMME_V> instead.
