Indeed. Also with glibc 2.3.6 and "gcc -Wall" I get warnings that fseeko is
not declared. This fixes it. Thanks for explaining.

Ensure fseeko, ftello are declared on glibc systems.
* modules/fflush (configure.ac-early): Require AC_FUNC_FSEEKO.
* modules/fseeko (configure.ac-early): Likewise.
* modules/ftello (configure.ac-early): Likewise.
* m4/fflush.m4 (gl_REPLACE_FFLUSH): Don't define HAVE_FSEEKO, rely on
AC_FUNC_FSEEKO for this.
* m4/fseeko.m4 (gl_FUNC_FSEEKO): Inline gl_CHECK_FSEEKO.
(gl_CHECK_FSEEKO): Remove macro.
