-/* Close STREAM.  Return 0 if successful, EOF (setting errno)
-   otherwise.  A failure might set errno to 0 if the error number
-   cannot be determined.
-
-   A failure with errno set to EPIPE may or may not indicate an error
-   situation worth signaling to the user.  See the documentation of the
-   close_stdout_set_ignore_EPIPE function for details.
-
-   If a program writes *anything* to STREAM, that program should close
-   STREAM and make sure that it succeeds before exiting.  Otherwise,
-   suppose that you go to the extreme of checking the return status
-   of every function that does an explicit write to STREAM.  The last
-   printf can succeed in writing to the internal stream buffer, and yet
-   the fclose(STREAM) could still fail (due e.g., to a disk full error)
-   when it tries to write out that buffered data.  Thus, you would be
-   left with an incomplete output file and the offending program would
-   exit successfully.  Even calling fflush is not always sufficient,
-   since some file systems (NFS and CODA) buffer written/flushed data
-   until an actual close call.
-
-   Besides, it's wasteful to check the return value from every call
-   that writes to STREAM -- just let the internal stream state record
-   the failure.  That's what the ferror test is checking below.  */
