This has come as something of a shock to me: it seems I've been living
in a dream world in which off_t was always 64 bits and large files were
supported by default :-)

The AC_SYS_LARGEFILE macro seems to be a relatively new addition to
autoconf (i.e. not in 2.13), but I'll see what I can do about enabling
large file support in GHC.
