FastMM4 & C++Builder 11.3 & IntraWeb 15.6.7

Has anyone successfully used FastMM4 with C++Builder 11.3 and IntraWeb 15.6.7 (or even IW 16)?

I followed the instructions in FastMM4BCB.cpp. I get many compiler errors, like these:


[bcc32 Error] typeinfo.h(154): E2367 Can't inherit RTTI class from non-RTTI base 'exception'
    typeinfo.h(154): class  bad_cast : public std::exception {};

[bcc32 Error] xlocale(670): E2238 Multiple declaration for 'codecvt&tchar16_t,char,int&t::in(int &,const char *,const char *,const char * &,char16_t *,char16_t *,char16_t * &) const'
    xlocale(667): 
result  in(_Statype& _State,

const _Byte *_First1, const _Byte *_Last1, const _Byte *& _Mid1,
_Elem *_First2, _Elem *_Last2, _Elem *& _Mid2) const
{ // convert bytes [_First1, _Last1) to [_First2, _Last)
return (do_in(_State,
_First1, _Last1, _Mid1, _First2, _Last2, _Mid2));
}



Any advice?
