I'm not a developer, so I don't know the details, but I ran "man 2 open"
on a Solaris 8 box and it does seem to support this:

     O_LARGEFILE
           If set, the offset maximum in the open  file  descrip-
           tion  is  the  largest  value  that can be represented
           correctly in an object of type off64_t.

But there might be other issues besides just opening the file with the
right flag.  Also, there may be differences between 32-bit and 64-bit
platforms (normally you shouldn't have problems with large files on a
64-bit machine).
