4025 * Boilerplate macros for initializing and accessing interpreter-local

4032 * "DynaLoader::_guts" XS_VERSION
89ca4ac7
JH		 4033 * 2. Declare a typedef named my_cxt_t that is a structure that contains
4034 * all the data that needs to be interpreter-local.
4035 * 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
4036 * 4. Use the MY_CXT_INIT macro such that it is called exactly once
4037 * (typically put in the BOOT: section).
4038 * 5. Use the members of the my_cxt_t structure everywhere as
4039 * MY_CXT.member.
4040 * 6. Use the dMY_CXT macro (a declaration) in all the functions that
4041 * access MY_CXT.
