It looks like a 64-bit issue indeed: 4912214227121058 in hex is
0x1173A2001173A2L, so the real value apparently should be 0x1173A2.
I tried reproducing this on the SF compile farm (Debian 3.0),
with stock Python 2.3.5, but I couldn't: it just works correctly
there. So there must be something wrong with the build process,
the C library, or the kernel.
It would be helpful to get the preprocessor output for posixmodule.i.
I'll include the relevant fragments from SF below; on the real build
environment, you should see the same (somewhat differently formatted).
One cause for these results would be if a 64-bit struct statvfs
would be used to call the 32-bit statvfs(2).
