You beat me to it. O_LARGEFILE should be considered part of Linux system
internals and not be used directly by software intended to be portable.

My educated guess is, that if you include '#define _FILE_OFFSET_BITS 64'
into every .c file (preferably by config.h) in openssh distribution or
just use  '-D_FILE_OFFSET_BITS=64' while compiling it, it would work just
fine with >2G files assuming you have glibc >= 2.1 and kernel >=2.4 (or
64 bit hardware, but then you won't need _FILE_OFFSET_BITS).
