I checked around with some kernel/glibc gurus in Red Hat, and the
consensus seemed to be that we'd be better off to bypass fprintf() and
just send message strings to stderr using write() --- ie, instead of
elog.c doing

            fprintf(stderr, "%s", buf.data);


            write(fileno(stderr), buf.data, strlen(buf.data));

Anyone have any comments on possible portability risks?  In particular,
will this work on Windows?
