>> test_nmt_locationprinting.cpp defines method test_for_dead_c_heap_block unconditionally, but this method is only ever used on Linux. In the gcc windows build this fires an unused method warning and breaks the gtest suite. Since this is never used outside of Linux, make this method's definition only appear on Linux to avoid polluting code on other platforms
