Octave can be built on windows using octave binary itself with help from the 
msys2
See
http://octave.1599824.n4.nabble.com/Octave-build-on-windows-using-octave-binary-itself-td4676652.html

Note that this can be done completely on mingw tool-chains.

In some occasion, one can use dll files from mingw that are built by msvc 
and one can use dll files from msvc that are built by mingw.

I do not know that the above is possible on current octave for windows (mingw 
build).
