Someone (Russ Allbery) recently helped me with this, so I thought I might
as well try answering my own question in case anyone else has this
problem.  The basic answer seems to be to define _LARGEFILE_SOURCE and
_FILE_OFFSET_BITS=64.  In fact, looking at Python's we see:


so just compile everything with -D_LARGEFILE_SOURCE and
-D_FILE_OFFSET_BITS=64.  If using distutils, adding

define_macros=[("_LARGEFILE_SOURCE", 1), ("_FILE_OFFSET_BITS", 64)]

when declaring the ext_modules does something similar and seems to work.

    Again, this is a bit ad hoc, but seems to work, and I don't know of a
better way.
