5071/* Static inline funcs that depend on includes and declarations above.
5072 Some of these reference functions in the perl object files, and some
5073 compilers aren't smart enough to eliminate unused static inline
5074 functions, so including this file in source code can cause link errors
5075 even if the source code uses none of the functions. Hence including these
5076 can be be suppressed by setting PERL_NO_INLINE_FUNCTIONS. Doing this will
5077 (obviously) result in unworkable XS code, but allows simple probing code
5078 to continue to work, because it permits tests to include the perl headers
5079 for definitions without creating a link dependency on the perl library
5080 (which may not exist yet).
