4141	* Boilerplate macros for initializing and accessing interpreter-local

4145	*
4146	* Code that uses these macros is responsible for the following:
4147	* 1. #define MY_CXT_KEY to a unique string, e.g.
4148	* "DynaLoader::_guts" XS_VERSION
4149	* 2. Declare a typedef named my_cxt_t that is a structure that contains
4150	* all the data that needs to be interpreter-local.
4151	* 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
4152	* 4. Use the MY_CXT_INIT macro such that it is called exactly once
4153	* (typically put in the BOOT: section).
4154	* 5. Use the members of the my_cxt_t structure everywhere as
4155	* MY_CXT.member.
4156	* 6. Use the dMY_CXT macro (a declaration) in all the functions that
4157	* access MY_CXT.
