We decided yesterday in the release team meeting to do an upgrade of the MinGW toolchain. That is, the MinGW toolchain we'll be testing & releasing with is
(This is basically the same configuration we've had before, just rev8 instead of rev1).
Other mingw toolchains _might_ work of course too. Anyhow, if you just want to go with the mainstream you should probably use the above.
For a 64 bit toolchain I suggest to use
However, we're concentrating efforts on 32 bit for now.
