It may seem like that at first glance, but it's not actually the case. 
OpenWatcom does supply swprintf_s(), but only for C source code, not for 
C++.  I.e. it's in <wchar.h>, but not available via its C++ equivalent, 
<cwchar>.

. Moreover, it's not just

I see no such problem here.  Maybe your version of mingw64 is outdated?

(For reference, I'm using the current version of the MinGW64 headers as 
installed by Cygwin, from package mingw64-x86_64-headers-5.0.2-1).
