-dnl From Jim Meyering
-dnl Using code from emacs, based on suggestions from Paul Eggert
-dnl and Ulrich Drepper.
-
-dnl Find out how to determine the number of pending output bytes on a stream.
-dnl glibc (2.1.93 and newer) and Solaris provide __fpending.  On other systems,
-dnl we have to grub around in the FILE struct.
