OK. I made a fresh clone from OpenWrt and build from scratch. Now when I
run the test program it segfault when trying to get APR time. I'll
follow up with that later today.

Maybe I had some old libtool cruft lying around, I don't know.

I looked at APR source but it doesn't seem to redefine gettimeofday. It
only uses it here:

APR_DECLARE(apr_time_t) apr_time_now(void)
{
    struct timeval tv;
    gettimeofday(&tv, NULL);
    return tv.tv_sec * APR_USEC_PER_SEC + tv.tv_usec;
}

Will let you all know how it goes :) Thanks again!
