+Downstream-only patch to restore the extern ABI for functions
+like fprintf that use the FILE * type.  Rebuilds of applications
+receive ABI change reports because of this installed header change
+(indirect subtype change in libabigail terms), and given that
+this part of struct _IO_FILE is strictly internal, there is no
+need to expose this change to installed headers.
