+/* 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
+   category 3.  */
