/* Set up the following warnings, based on which modules are in use.

274

GNU Coding Standards discourage the use of fseek, since it imposes

275

an arbitrary limitation on some 32-bit hosts. Remember that the

276

fseek module depends on the fseeko module, so we only have three

277

cases to consider:

278

279

1. The developer is not using either module. Issue a warning under

280

GNULIB_POSIXCHECK for both functions, to remind them that both

281

functions have bugs on some systems. _GL_NO_LARGE_FILES has no

282

impact on this warning.

283

284

2. The developer is using both modules. They may be unaware of the

285

arbitrary limitations of fseek, so issue a warning under

286

GNULIB_POSIXCHECK. On the other hand, they may be using both

287

modules intentionally, so the developer can define

288

_GL_NO_LARGE_FILES in the compilation units where the use of fseek

289

is safe, to silence the warning.

290

291

3. The developer is using the fseeko module, but not fseek. Gnulib

292

guarantees that fseek will still work around platform bugs in that

293

case, but we presume that the developer is aware of the pitfalls of

294

fseek and was trying to avoid it, so issue a warning even when

295

GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be

296

defined to silence the warning in particular compilation units.

297

In C++ compilations with GNULIB_NAMESPACE, in order to avoid that

298

fseek gets defined as a macro, it is recommended that the developer

299

uses the fseek module, even if he is not calling the fseek function.

300

301

Most gnulib clients that perform stream operations should fall into

302

category 3. */
