+Subject: [PATCH] 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.
