[PATCH] A couple minor changes to support sanitizers on FreeBSD 9.2

[Alexey Samsonov]

  > If we define _SIZE_T_DECLARED for this set of sources, then we need to define size_t in each of the sources which is a kind of mass change--no good. And then we would need both the CMakeLists.txt and the sources, so what's the profit?

  What if we compile all the sources and all the tests with "_D_SIZE_T_DECLARED" and "-Dsize_t=unsigned" (or -Dsize_t=__SIZE_TYPE__)?
