/* 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. */
