576 /* Set up the following warnings, based on which modules are in use.
577 GNU Coding Standards discourage the use of fseek, since it imposes
578 an arbitrary limitation on some 32-bit hosts. Remember that the
579 fseek module depends on the fseeko module, so we only have three
580 cases to consider:
581
582 1. The developer is not using either module. Issue a warning under
583 GNULIB_POSIXCHECK for both functions, to remind them that both
584 functions have bugs on some systems. _GL_NO_LARGE_FILES has no
585 impact on this warning.
586
587 2. The developer is using both modules. They may be unaware of the
588 arbitrary limitations of fseek, so issue a warning under
589 GNULIB_POSIXCHECK. On the other hand, they may be using both
590 modules intentionally, so the developer can define
591 _GL_NO_LARGE_FILES in the compilation units where the use of fseek
592 is safe, to silence the warning.
593
594 3. The developer is using the fseeko module, but not fseek. Gnulib
595 guarantees that fseek will still work around platform bugs in that
596 case, but we presume that the developer is aware of the pitfalls of
597 fseek and was trying to avoid it, so issue a warning even when
598 GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be
599 defined to silence the warning in particular compilation units.
600 In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
601 fseek gets defined as a macro, it is recommended that the developer
602 uses the fseek module, even if he is not calling the fseek function.
603
604 Most gnulib clients that perform stream operations should fall into
605 category 3. */
