[mxe-octave] Can WARNING: --enable-64 implies --enable-windows-64 be ignored? for native build

[Tatsuro MATSUOKA]

I am trying to build octave with large-array on Ubuntu 14.04 
using mxe-octave native build.

I have followed instruction on the Wiki.
http://wiki.octave.org/MXE

#**********
cd ~/work/octave/mxe-octave
hg clone http://hg.octave.org/mxe-octave/ mxe-octave-lunix-e64
cd ~/work/octave/mxe-octave/mxe-octave-lunix-e64
autoconf
./configure --enable-64 --enable-native-build --enable-pic-flag 
host_alias=gnu-linux --enable-openblas --enable-jit --enable-octave=stable
LANG=C make
LANG=C make openblas
cd usr/lib
mv libblas.so libblas.so.reference
ln -s libopenblas.so libblas.so
#**********

At ./configure I have seen the waring

configure: WARNING: --enable-64 implies --enable-windows-64
gnu-linux

config.log also said that
configure:3220: WARNING: --enable-64 implies --enable-windows-64

Is the above able to be ignored?
