Hi Toma=BE,
well this problem would have been appeared soon or later. There is two=20
way of resolving that matter. First we could put by default some headers=20
in the test code but i'm afraid of the border effects of this solution.=20
The other would be to permit providing of additional headers needed for=20
the test. So i think i'll implement the second as sooon as possible.

In the general case it's better to check for a function in the lib as=20
the same in the header is somewhat a trick.

BTW i'm surprised it doesn't work under freebsd as the author of=20
libmemcache is a committer.
