about gcc itself.
since gcc is compiled with -static-libgcc -static-libstdc++, it should not be a
problem tbh.

--- Comment #1 from cqwrteur ---
I think this is probably the reason why I got the last error, because canadian
cross toolchains install the wrong multilibs for dlls.
I personally suggest libstdc++-6.dll should install in /lib just like Linux

While in C++20, the complier thinks it's unnecessary to instatiate a new
