New Revision: 76638

Added:
   pypy/branch/fast-ctypes/pypy/module/_ctypes/test/_ctypes_test.c
   pypy/branch/fast-ctypes/pypy/module/_ctypes/test/conftest.py
   pypy/branch/fast-ctypes/pypy/module/_ctypes/test/test_loading.py
Log:
import and modify test_loading from lib_pypy/_ctypes
tests pass but some lines have to be changed in modified/ctypes (temporary, not commited)
