[PATCH] Fix tests to be more specific.

[Samuel Benzaquen]

  Sorry for the rushed change.
  I wasn't the one that "fixed" this the first time so I didn't really know what the problem was.
  There are indeed extra declarations in every compilation unit, but not just in MSVC. In MSVC they happen to match with the very generic matcher I was using on the test.
  This should fix it correctly for both.
