  After that the config.h contains:

// #define _RWSTD_NO_WCTOMB - the function is found in <cstdlib>
#define _RWSTD_NO_WCTOMB - the function is not found in <cwchar>

  It is incorrect.

  The same concern wcstombs.

  I didn't found platform where wctomb is declared in <cwchar> header.

You're right, wctomb is only supposed to be declared in stdlib.h.
It got probably confused with wctob.

  Shall we remove checking of theese functions in wchar.h ?

I think that makes sense.
