But there is one:

EXT MGVTBL PL_vtbl_regdata = {0, 0, MEMBER_TO_FPTR(Perl_magic_regdata_cnt), 0, 0};

#ifdef STRUCT_MGVTBL_DEFINITION
STRUCT_MGVTBL_DEFINITION;
#else
struct mgvtbl {
    int		(CPERLscope(*svt_get))	(pTHX_ SV *sv, MAGIC* mg);
    int		(CPERLscope(*svt_set))	(pTHX_ SV *sv, MAGIC* mg);
    U32		(CPERLscope(*svt_len))	(pTHX_ SV *sv, MAGIC* mg);
    int		(CPERLscope(*svt_clear))(pTHX_ SV *sv, MAGIC* mg);
    int		(CPERLscope(*svt_free))	(pTHX_ SV *sv, MAGIC* mg);
};
#endif
