+	fflush: adjust to glibc 2.28 libio.h removal
+	Problem reported by Daniel P. Berrangé in:
+	https://lists.gnu.org/r/bug-gnulib/2018-03/msg00000.html
+	* lib/fbufmode.c (fbufmode):
+	* lib/fflush.c (clear_ungetc_buffer_preserving_position)
+	(disable_seek_optimization, rpl_fflush):
+	* lib/fpending.c (__fpending):
+	* lib/fpurge.c (fpurge):
+	* lib/freadable.c (freadable):
+	* lib/freadahead.c (freadahead):
+	* lib/freading.c (freading):
+	* lib/freadptr.c (freadptr):
+	* lib/freadseek.c (freadptrinc):
+	* lib/fseeko.c (fseeko):
+	* lib/fseterr.c (fseterr):
+	* lib/fwritable.c (fwritable):
+	* lib/fwriting.c (fwriting):
+	Check _IO_EOF_SEEN instead of _IO_ftrylockfile.
+	* lib/stdio-impl.h (_IO_IN_BACKUP) [_IO_EOF_SEEN]:
+	Define if not already defined.
