732 /* Set up the following warnings, based on which modules are in use.
733    GNU Coding Standards discourage the use of fseek, since it imposes
734    an arbitrary limitation on some 32-bit hosts.  Remember that the
735    fseek module depends on the fseeko module, so we only have three
736    cases to consider:
737 
738    1. The developer is not using either module.  Issue a warning under
739    GNULIB_POSIXCHECK for both functions, to remind them that both
740    functions have bugs on some systems.  _GL_NO_LARGE_FILES has no
741    impact on this warning.
742 
743    2. The developer is using both modules.  They may be unaware of the
744    arbitrary limitations of fseek, so issue a warning under
745    GNULIB_POSIXCHECK.  On the other hand, they may be using both
746    modules intentionally, so the developer can define
747    _GL_NO_LARGE_FILES in the compilation units where the use of fseek
748    is safe, to silence the warning.
749 
750    3. The developer is using the fseeko module, but not fseek.  Gnulib
751    guarantees that fseek will still work around platform bugs in that
752    case, but we presume that the developer is aware of the pitfalls of
753    fseek and was trying to avoid it, so issue a warning even when
754    GNULIB_POSIXCHECK is undefined.  Again, _GL_NO_LARGE_FILES can be
755    defined to silence the warning in particular compilation units.
756    In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
757    fseek gets defined as a macro, it is recommended that the developer
758    uses the fseek module, even if he is not calling the fseek function.
