Hit send too fast, the 64bit results should say:
* 64bit mingw-w64 mingw-builds => no implicit link to `libgcc_s_sjlj-1.dll`
* 64bit msys2 mingw64 => no implicit link to `libgcc_s_seh-1.dll`
If it's not clear, I tested with the threads-win32 and sjlj toolchains from
mingw-w64 mingw-builds and the mingw-w64-{i686,x86_64}-gcc 4.9.0-4 pacman
packages from msys2.
