I'll have a look at the stoi problem today.

MinGW should be using gcc-4.9.3. That's what's on Debian Jessie and master compiles fine there, so I don't think that it's a C++ support problem.

That said, MinGW64 seems to have a lot more mind-share recently than MinGW so perhaps we should look at it. I've no idea at this point whether it can be a "drop-in" replacement or would require substantial reworking of the build scripts.
