Large file support and stat vs stat64 in extension modules

Hi, I'm writing an extension module in C and am having trouble
statting files longer than 2GB, at least under linux (Redhat 7.2, intel).
If I simply use the stat() system call, I get an EOVERFLOW error
(OSError: [Errno 75] Value too large for defined data type). It seems
that I should be using the newer stat64() call, but:
1. posixmodule.c appears just to use plain old stat(). I cannot figure
out why I get errors and it works fine. Quite a mystery.
2. I don't know what #if defined's to put in to choose between stat and
stat64 correctly.
Does anyone know how to correctly stat a file within an extension module?
Why does:
struct stat st;
res = stat("bigfile", &st)
not work for me, but in posixmodule.c the same thing (apparently) is done
and works fine?
