You can already do so knowing your OS/compiler, but it is not very visible
in 2.5 as this has not received much if any testing and there may well be
many issues in file size calculation.

In Squid-3.0 there will be a experimental configure option to enable 64
bit file I/O on the 32 bit systems we know how to, but is still considered
experimental until verified what happens on files >2GB in different
conditions.

Squid does quite many calculations on file size, and all of these needs to
be verified to use size_t (or ssize_t) and never typecast explicitly or
implicitly to any of the C/C++ base types.
