5107 Some of these reference functions in the perl object files, and some
5108 compilers aren't smart enough to eliminate unused static inline
5109 functions, so including this file in source code can cause link errors
5110 even if the source code uses none of the functions. Hence including these
5111 can be be suppressed by setting PERL_NO_INLINE_FUNCTIONS. Doing this will
5112 (obviously) result in unworkable XS code, but allows simple probing code
5113 to continue to work, because it permits tests to include the perl headers
5114 for definitions without creating a link dependency on the perl library
5115 (which may not exist yet).
