No no, my script (emacs-w64-build.sh) downloads the source, run autogen.sh and

eval "${emacs_build_env}" ./configure --prefix="/${PREFIXNAME}" \
         --build=x86_64-w64-mingw32 \
         --without-imagemagick \
         --without-dbus \
         --without-pop \
         --with-modules

make ${MAKE_OPT}

where 

emacs_build_env is, basically,

  CPPFLAGS="-D_FORTIFY_SOURCE=2 -D__USE_MINGW_ANSI_STDIO=1" \
  CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe"

MAKE_OPT is, basically, '-j 6'. Now I removed '-D_FORTIFY_SOURCE=2'.

Then, the script creates the .7z package.

The script 'makepkg-mingw' belongs to MSYS2 installation. If you remember, 
MSYS2 uses PKGBUILD scripts as in ArchLinux and 'makepkg-mingw' is used to 
build MinGW packages (there is also a 'makepkg' script to build _native_ MSYS2 
packages). See https://github.com/msys2/msys2/wiki/Creating-packages#building.
