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