Do not know whether it is an issue for mingw-w64 or libstdc++

This seems like a binutils ld bug rather than a libstdc++ bug ...

cygwin was improved here:

It might be the case mingw linker script is broken ....

This is mingw-w64, not newlib-cygwin

I think he's suggesting that we have to apply the same solution to mingw that Corinna applied to Cygwin.

I doubt this is the issue with ld linker. More likely to be a libstdc++ issue.
