        I think I know about this one, as I think I was the one
        who lobbied for its inclusion; see my initial post:
        http://www.fltk.org/newsgroups.php?gfltk.bugs+v:3147

        ..and the followup thread:
        http://www.fltk.org/newsgroups.php?gfltk.bugs+T+QFILE_OFFSET_BITS

        In short, the flag resolves a problem with 32bit machines were not able
        to properly browse files on remote NFS servers that were 64bit machines.

        IIRC the flag enables the local OS to maintain 64bit values for
        certain operations to ensure proper management of 64bit values in
        such situations, so that the browsers work properly in all cases.
