Issue a warning under 508 GNULIB_POSIXCHECK for both functions, to remind them that both 509 functions have bugs on some systems. _GL_NO_LARGE_FILES has no 510 impact on this warning. 511 512 2. The developer is using both modules. They may be unaware of the 513 arbitrary limitations of fseek, so issue a warning under 514 GNULIB_POSIXCHECK. On the other hand, they may be using both 515 modules intentionally, so the developer can define 516 _GL_NO_LARGE_FILES in the compilation units where the use of fseek 517 is safe, to silence the warning. 518 519 3. The developer is using the fseeko module, but not fseek. Gnulib 520 guarantees that fseek will still work around platform bugs in that 521 case, but we presume that the developer is aware of the pitfalls of 522 fseek and was trying to avoid it, so issue a warning even when 523 GNULIB_POSIXCHECK is undefined.
