That's actually file. "_readdir_pyx" is only meant to be used on
platforms that use "readdir()" which is cygwin and POSIX, not win32.

What I don't understand is why it is *trying* to build it. At least
according to my setup.py:

if sys.platform == 'win32':
    add_pyrex_extension('bzrlib._dirstate_helpers_c',
                         libraries=['Ws2_32']
                       )
...
    add_pyrex_extension('bzrlib._walkdirs_win32',
                        define_macros=[('WIN32', None)])
else:
    add_pyrex_extension('bzrlib._dirstate_helpers_c')
    add_pyrex_extension('bzrlib._readdir_pyx')


Which says that if "sys.platform == 'win32'" build the "_walkdirs_win32"
extension, otherwise build the "_readdir_pyx" extension.

What is your sys.platform?
