# Note: uses the CFFI out-of-line ABI mode. We can't use the API
# mode because ffi.compile() needs to run the compiler, which
# needs 'subprocess', which needs 'msvcrt' and '_subprocess',
# which depend on '_pypy_winbase_cffi' already.
#
# Note that if you need to regenerate _pypy_winbase_cffi and
# can't use a preexisting PyPy to do that, then running this
# file should work as long as 'subprocess' is not imported
# by cffi. I had to hack in 'cffi._pycparser' to move an
#'import subprocess' to the inside of a function. (Also,
# CPython+CFFI should work as well.)
#
# This module supports both msvcrt.py and _subprocess.py.
