I suppose that you are talking about MinGW (<a href="http://www.mingw.org" target="_blank">www.mingw.org</a>) all along<br>
and not about MinGW-w64 (<a href="http://www.mingw-w64.org" target="_blank">www.mingw-w64.org</a>) which supports the features<br>
you are missing.<br>
<br>

<br>
Oh, well. You are talking about "everything that is not MSVC++". Ok.<br>
<br>

<br>
I have no idea how cross-compiling from other OS can solve shortcomings<br>
on the *runtime* libraries of a toolchain.<br>

Thanks, I knew that you consider MinGW* "low-value" all along. MinGW-w64<br>
is well ahead of MSVC++ on C++ language and library support, and it is<br>
very likely that it will remain that way, but you take every chance to<br>
bad-mouth it to promote MSVC++ support on LLVM/Clang.<br>
