A bit more grumpy about bad texinfo, though.

+   you go to the extreme of checking the return status of every function
+   that does an explicit write to stdout.  The last printf can succeed in
+   writing to the internal stream buffer, and yet the fclose(stdout) 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.
+
+   Besides, it's wasteful to check the return value from every call
+   that writes to stdout -- just let the internal stream state record
+   the failure.  That's what the ferror test is checking below.
+
+   It's important to detect such failures and exit nonzero because many
+   tools (most notably `make' and other build-management systems) depend
+   on being able to detect failure in other tools via their exit status.  */
