I don’t think that reposting parts of you OP helps to reduce the confusion. Let me try to address the points nonetheless.

You should read the [Windows instructions](https://github.com/JuliaLang/julia/blob/master/doc/build/windows.md) if you try to build Julia on Windows. But no, `Make.user` means `Make.user` not `Make.inc`.

There is no doubt that Julia + MKL has, in many cases, superior performance over Julia + OpenBLAS (see for example my matrix multiplication benchmark [here](https://discourse.julialang.org/t/openblas-vs-mkl/17362/4)). By limitations I’m refering to what is listed as limitations on [MKL.jl’s github page](https://github.com/JuliaComputing/MKL.jl), in particular the first point.

Again, if you have issues building Julia on Windows, it’d be great if you could share what those issues are. This way I (or someone else) might be able to provide help.
