 617 /* Set up the following warnings, based on which modules are in use.
 618    GNU Coding Standards discourage the use of fseek, since it imposes
 619    an arbitrary limitation on some 32-bit hosts.  Remember that the
 620    fseek module depends on the fseeko module, so we only have three
 621    cases to consider:
 622
 623    1. The developer is not using either module.  Issue a warning under
 624    GNULIB_POSIXCHECK for both functions, to remind them that both
 625    functions have bugs on some systems.  _GL_NO_LARGE_FILES has no
 626    impact on this warning.
 627
 628    2. The developer is using both modules.  They may be unaware of the
 629    arbitrary limitations of fseek, so issue a warning under
 630    GNULIB_POSIXCHECK.  On the other hand, they may be using both
 631    modules intentionally, so the developer can define
 632    _GL_NO_LARGE_FILES in the compilation units where the use of fseek
 633    is safe, to silence the warning.
 634
 635    3. The developer is using the fseeko module, but not fseek.  Gnulib
 636    guarantees that fseek will still work around platform bugs in that
 637    case, but we presume that the developer is aware of the pitfalls of
 638    fseek and was trying to avoid it, so issue a warning even when
 639    GNULIB_POSIXCHECK is undefined.  Again, _GL_NO_LARGE_FILES can be
 640    defined to silence the warning in particular compilation units.
 641    In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
 642    fseek gets defined as a macro, it is recommended that the developer
 643    uses the fseek module, even if he is not calling the fseek function.
 644
 645    Most gnulib clients that perform stream operations should fall into
 646    category 3.  */
