318 /* Set up the following warnings, based on which modules are in use.
319 GNU Coding Standards discourage the use of fseek, since it imposes
320 an arbitrary limitation on some 32-bit hosts. Remember that the
321 fseek module depends on the fseeko module, so we only have three
322 cases to consider:
323
324 1. The developer is not using either module. Issue a warning under
325 GNULIB_POSIXCHECK for both functions, to remind them that both
326 functions have bugs on some systems. _GL_NO_LARGE_FILES has no
327 impact on this warning.
328
329 2. The developer is using both modules. They may be unaware of the
330 arbitrary limitations of fseek, so issue a warning under
331 GNULIB_POSIXCHECK. On the other hand, they may be using both
332 modules intentionally, so the developer can define
333 _GL_NO_LARGE_FILES in the compilation units where the use of fseek
334 is safe, to silence the warning.
335
336 3. The developer is using the fseeko module, but not fseek. Gnulib
337 guarantees that fseek will still work around platform bugs in that
338 case, but we presume that the developer is aware of the pitfalls of
339 fseek and was trying to avoid it, so issue a warning even when
340 GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be
341 defined to silence the warning in particular compilation units.
342 In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
343 fseek gets defined as a macro, it is recommended that the developer
344 uses the fseek module, even if he is not calling the fseek function.
345
346 Most gnulib clients that perform stream operations should fall into
347 category 3. */
