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!
