This function fails on seekable stdin, stdout, and stderr: cygwin <= 1.5.24.
+@item
+On platforms where @code{off_t} is a 32-bit type, @code{fseeko} does not work
+correctly with files larger than 2 GB. (Cf. @code{AC_SYS_LARGEFILE}.)

Portability problems not fixed by Gnulib:

@item
-On platforms where @code{off_t} is a 32-bit type, @code{fseeko} does not work
-correctly with files larger than 2 GB. The fix is to use the
-@code{AC_SYS_LARGEFILE} macro.
-@item
On platforms where @code{off_t} is a 64-bit type, but @code{fseeko} is
not present, stream operations on files larger than 2 GB silently do
the wrong thing. This affects BSD/OS, which is mostly obsolete.
