echo Before running prepare_libffi.bat 
echo   LIBFFI_SOURCE environment variable must be set to the location of
echo     of python-source-deps clone of libffi branch
echo   VCVARSALL must be set to location of vcvarsall.bat
echo   cygwin must be installed (see below)
echo   SH environment variable must be set to the location of sh.exe
echo.
echo Tested with cygwin-x86 from https://www.cygwin.com/install.html
echo Select http://mirrors.kernel.org as the download site
echo Include the following cygwin packages in cygwin configuration:
echo     make, autoconf, automake, libtool, dejagnu
echo.
echo NOTE: dejagnu is only required for running tests.
echo       set LIBFFI_TEST=1 to run tests (optional)
