You may be the first one to try this - as far as I know, Bino+Equalizer
has only been used on Linux and Mac OS so far.

I did not yet succeed to cross-build Equalizer using mingw-cross-env.
One unsolved problem is that I run into 'undefined reference to vtable
for eq::fabric::Object' errors during linking, and I have no idea how
to solve them. See <https://github.com/Eyescale/Equalizer/issues/7> for
more information.

Another problem will probably be that Equalizer does not really support
static libraries (as far as I know), but mingw-cross-env is purely
based on static libraries.

You could try to compile and link with the prebuilt Equalizer binaries
for Windows instead. This should be possible if you either have
Equalizer.pc/Collage.pc files in your PKG_CONFIG_PATH_i686_pc_mingw32
path, or if you set the libEqualizer_CFLAGS and libEqualizer_LIBS
environment variables before running Bino's configure script.

But I never tried that.

Yes, the instructions need to be updated. I hope mingw-cross-env will
get around to release a new stable version soon.
