I think the questions was about MKL BLAS with MinGW.

WADA, see Windows FAQ 8.2 - in general, you don't need to compile R against a particular BLAS - you just use shared BLAS and put your favorite BLAS implementation (like MKL) instead of Rblas.dll. The instructions you quote are not for you - they are for unix. I did not use MKL on Windows myself (my tests on OSX indicated that it's slower than ATALS and thus not worth the hassle), so you'll have to try it for yourself.

Cheers,
Simon
