5408 Some of these reference functions in the perl object files, and some
5409 compilers aren't smart enough to eliminate unused static inline
5410 functions, so including this file in source code can cause link errors
5411 even if the source code uses none of the functions. Hence including these
5412 can be be suppressed by setting PERL_NO_INLINE_FUNCTIONS. Doing this will
5413 (obviously) result in unworkable XS code, but allows simple probing code
5414 to continue to work, because it permits tests to include the perl headers
5415 for definitions without creating a link dependency on the perl library
5416 (which may not exist yet).

5834 * "DynaLoader::_guts" XS_VERSION
f16dd614 5835 * XXX in the current implementation, this string is ignored.
89ca4ac7

5837 * all the data that needs to be interpreter-local.
5838 * 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
5839 * 4. Use the MY_CXT_INIT macro such that it is called exactly once
5840 * (typically put in the BOOT: section).
5841 * 5. Use the members of the my_cxt_t structure everywhere as
5842 * MY_CXT.member.
