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. */
