I think this is fixed in lenny already. The current sigdie function
reads:

void
sigdie(const char *fmt,...)
{
#ifdef DO_LOG_SAFE_IN_SIGHAND
        va_list args;

        va_start(args, fmt);
        do_log(SYSLOG_LEVEL_FATAL, fmt, args);
        va_end(args);
#endif
        _exit(1);
}

defines.h has:

#if defined(HAVE_OPENLOG_R) && defined(SYSLOG_DATA_INIT) && \
    defined(SYSLOG_R_SAFE_IN_SIGHAND)
# define DO_LOG_SAFE_IN_SIGHAND
#endif

The easiest element of this conjunction to check is
SYSLOG_R_SAFE_IN_SIGHAND, which configure only defines on OpenBSD.
