Hmm.. I build regularly Emacs git on MSYS2 producing a W64 native build.

Usually I use the MSYS2 statements [1] to build using the PKGBUILD 
script in [2], in which I have added "-j3" to "make" (my machine is an 
old Athlon 64 X2 Dual Core).

Usually, all works and the build take about 30-40 minutes. To install it 
takes about the time to unpack an xz compressed tarball..
