There are differences between stable (4.4.0) and defalut (4.5.0).
For 4.4 as you wrote. BLAS etc libraries. should be prepared with 64 bit index.
For mxe-octave for stable (4.4) --enable-fortran-int64 ineviably required
for 64 bit index build for stable
For 4,5, one can use 64 bit index evenif BLAS etc. are built with 32bit index.
Thus --enable-fortran-int64 is not required for default (4.5) mxe build.

--enable64 --enable-windows64 and --enable-fortran-int64 for stable branch.

Perhaps 64 index for 64 bit binary will be default in the next major release.
I am not a developer but a one of heavy users.
I suspect that windows binary this release is built with 32 bit index is
intentional.
Developer will make a definite rely.
