In fact we already somewhat handle that in modperl_io_apache.h



#ifdef PERLIO_LAYERS
[...]
MP_INLINE void modperl_io_apache_init(pTHX);

#else /* #ifdef PERLIO_LAYERS */

#define modperl_io_apache_init(pTHX)

#endif /* #ifdef PERLIO_LAYERS */



but for some reason define doesn't do the trick, when it gets to do:

   const void *modperl_hack_io_apache_init =
      (const void *)modperl_io_apache_init;

should it be some magic VOID thing?

#define modperl_io_apache_init(pTHX) VOID
