--- Comment #1 from cqwrteur <unlvsur at live dot com> ---
I think this is probably the reason why I got the last error, because canad=
ian
cross toolchains install the wrong multilibs for dlls.

I personally suggest libstdc++-6.dll should install in /lib just like Linux=
 or
other POSIX compliant systems are doing. Or of course, it will break multil=
ibs.

Just add /lib or /lib64 to the environmental variable list on windows or in=
 the
registry with wine, it will work correctly and the operating system will fi=
nd
out the correct dll for both 32bit and 64bit libstdc++-6.dll=
