5101 Some of these reference functions in the perl object files, and some
5102 compilers aren't smart enough to eliminate unused static inline
5103 functions, so including this file in source code can cause link errors
5104 even if the source code uses none of the functions. Hence including these
5105 can be be suppressed by setting PERL_NO_INLINE_FUNCTIONS. Doing this will
5106 (obviously) result in unworkable XS code, but allows simple probing code
5107 to continue to work, because it permits tests to include the perl headers
5108 for definitions without creating a link dependency on the perl library
5109 (which may not exist yet).
