ATTRIBUTE_NORETURN is supported on all platforms (MSVS and GCC-like). It declares that a function will not return; instead, the thread or the whole process will terminate. ATTRIBUTE_COLD is supported starting with GCC 4.3. It declares that a function is supposed to be executed rarely. Rarely used error-handling functions and functions that emit messages to the error log should be tagged such.
