How odd. It looks as if libcurl didn't get the multi.o object added. Can you
verify that the link line in fact includes the multi.o object file when
libcurl is linked?

Or try this command line:

  nm $curlbuildroot/lib/.libs/libcurl.a | grep multi

It should show seven multi-related symbols.

Ah! Thanks for pointing this out. My mistake. I even made it include "test.h"
instead (which in turn includes <curl.h>).
