   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.  */
