The ChangeLog entry is not.  Only one space after PR, two spaces before <
and both cp and c-family subdirectories have their own ChangeLog entries,
so you need
	PR bootstrap/68271
	* parser.h (cp_token): Update pragma_kind to 8.
in cp/ChangeLog and
	PR bootstrap/68271
	* c-pragma.c (c_register_pragma_1): Update the gcc_assert to 256.
in c-family/ChangeLog.

Ok with those changes.

	Jakub
