391 /* Set up the following warnings, based on which modules are in use.
392 GNU Coding Standards discourage the use of fseek, since it imposes
393 an arbitrary limitation on some 32-bit hosts. Remember that the
394 fseek module depends on the fseeko module, so we only have three
397 1. The developer is not using either module. Issue a warning under
398 GNULIB_POSIXCHECK for both functions, to remind them that both
399 functions have bugs on some systems. _GL_NO_LARGE_FILES has no
400 impact on this warning.
402 2. The developer is using both modules. They may be unaware of the
403 arbitrary limitations of fseek, so issue a warning under
404 GNULIB_POSIXCHECK. On the other hand, they may be using both
405 modules intentionally, so the developer can define
406 _GL_NO_LARGE_FILES in the compilation units where the use of fseek
407 is safe, to silence the warning.
409 3. The developer is using the fseeko module, but not fseek. Gnulib
410 guarantees that fseek will still work around platform bugs in that
411 case, but we presume that the developer is aware of the pitfalls of
412 fseek and was trying to avoid it, so issue a warning even when
413 GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be
414 defined to silence the warning in particular compilation units.
415 In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
416 fseek gets defined as a macro, it is recommended that the developer
417 uses the fseek module, even if he is not calling the fseek function.
