474 /* Set up the following warnings, based on which modules are in use.
475 GNU Coding Standards discourage the use of fseek, since it imposes
476 an arbitrary limitation on some 32-bit hosts. Remember that the
477 fseek module depends on the fseeko module, so we only have three
480 1. The developer is not using either module. Issue a warning under
481 GNULIB_POSIXCHECK for both functions, to remind them that both
482 functions have bugs on some systems. _GL_NO_LARGE_FILES has no
483 impact on this warning.
485 2. The developer is using both modules. They may be unaware of the
486 arbitrary limitations of fseek, so issue a warning under
487 GNULIB_POSIXCHECK. On the other hand, they may be using both
488 modules intentionally, so the developer can define
489 _GL_NO_LARGE_FILES in the compilation units where the use of fseek
490 is safe, to silence the warning.
492 3. The developer is using the fseeko module, but not fseek. Gnulib
493 guarantees that fseek will still work around platform bugs in that
494 case, but we presume that the developer is aware of the pitfalls of
495 fseek and was trying to avoid it, so issue a warning even when
496 GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be
497 defined to silence the warning in particular compilation units.
498 In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
499 fseek gets defined as a macro, it is recommended that the developer
500 uses the fseek module, even if he is not calling the fseek function.
