windows 64bit "Unsupported 16-bit application" thingie

[coderofsalvation]

First of all, thank you (everybody) for this revolutionary cosmopolitan tech. I asked a friend of mine to run a binary in the console (he has windows 10):

buildscript

#!/bin/sh 
VERSION=0.9
APP=milkysynth
OBJECTS="wavread.c wavwrite.c cli.c"

test -z $COSMO_PATH && { echo "[e] COSMO_PATH env-var not set (should point to https://github.com/jart/cosmopolitan)"; exit 1; }
test -d cosmo || {
  mkdir cosmo && cd cosmo
  wget https://justine.lol/cosmopolitan/cosmopolitan.zip
  unzip -o cosmopolitan.zip 
}
test -f $APP.com && rm $APP.com
# this is basically the example from README.md
gcc -DVERSION=\"$VERSION\" -DCOSMO -g3 -Og -static -nostdlib -nostdinc -fno-pie -no-pie -mno-red-zone -pg \
    -fno-omit-frame-pointer -pg -mnop-mcount -I$COSMO_PATH/libc -I$COSMO_PATH/libc/isystem -I$COSMO_PATH -I./fake \
    -o $APP.com.dbg ${OBJECTS} -fuse-ld=bfd -Wl,-T,cosmo/ape.lds \
    -include cosmo/cosmopolitan.h cosmo/crt.o cosmo/ape.o cosmo/cosmopolitan.a
objcopy -S -O binary $APP.com.dbg $APP.com && ls -lah $APP.com

ps. I ran this on linux 64bit Lubuntu, where the binary runs fine.
