Fix STATIC_ASSERT macro when using multiple .proto files.
The __COUNTER__ macro (used for generating unique names) is at least supported
by gcc, clang and Visual Studio. With this change test_compiles.c is
compilable, since no more typedefs are redefined.
Compilers/Preprocessors not supporting __COUNTER__ error's are still possible
which are hopfully handled by the usage of __LINE__ in most sittuations.
Added unit test for the problem.
