How about this:

#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <string.h>

#define LOGFILE "/stdouttest.log"
#define TESTMSG "This is a test string\n"

int
main(int argc, char **argv, char **envp)
{
	FILE *logfile;
	int printerrno;
	char *printerror;
	int retval = EXIT_FAILURE;
	int result;

	/* Setup a log file */
	logfile = fopen(LOGFILE, "a");
	if (!logfile)
		exit(retval);
	
	fprintf(logfile, "Program %s started\n", argv[0]); 

	/* Print to stdout */
	result = fprintf(stdout, TESTMSG);

	/* Log results */
	if (result < 0) {
		printerrno = errno;
		printerror = strerror(printerrno);
		fprintf(logfile, "Printing failed (%i): %s\n",
			printerrno, printerror);
	} else if (result < strlen(TESTMSG)) {
		fprintf(logfile, "Printing was truncated to %i bytes\n", result);
	} else {
		fprintf(logfile, "Printing successful\n");
		retval = EXIT_SUCCESS;
	}

	/* We're done */
	fclose(logfile);
	exit(retval);
}

Sounds like a good idea...the upstream mailing list is very active.
