425 /* Set up the following warnings, based on which modules are in use.
426  GNU Coding Standards discourage the use of fseek, since it imposes
427  an arbitrary limitation on some 32-bit hosts. Remember that the
428  fseek module depends on the fseeko module, so we only have three
429  cases to consider:
430 
431  1. The developer is not using either module. Issue a warning under
432  GNULIB_POSIXCHECK for both functions, to remind them that both
433  functions have bugs on some systems. _GL_NO_LARGE_FILES has no
434  impact on this warning.
435 
436  2. The developer is using both modules. They may be unaware of the
437  arbitrary limitations of fseek, so issue a warning under
438  GNULIB_POSIXCHECK. On the other hand, they may be using both
439  modules intentionally, so the developer can define
440  _GL_NO_LARGE_FILES in the compilation units where the use of fseek
441  is safe, to silence the warning.
442 
443  3. The developer is using the fseeko module, but not fseek. Gnulib
444  guarantees that fseek will still work around platform bugs in that
445  case, but we presume that the developer is aware of the pitfalls of
446  fseek and was trying to avoid it, so issue a warning even when
447  GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be
448  defined to silence the warning in particular compilation units.
449  In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
450  fseek gets defined as a macro, it is recommended that the developer
451  uses the fseek module, even if he is not calling the fseek function.
452
