怎样识别名称：

#if defined(__clang__)/* Clang/LLVM. ---------------------------------------------- */#elif defined(__ICC) || defined(__INTEL_COMPILER)/* Intel ICC/ICPC. ------------------------------------------ */#elif defined(__GNUC__) || defined(__GNUG__)/* GNU GCC/G++. --------------------------------------------- */#elif defined(__HP_cc) || defined(__HP_aCC)/* Hewlett-Packard C/aC++. ---------------------------------- */#elif defined(__IBMC__) || defined(__IBMCPP__)/* IBM XL C/C++. -------------------------------------------- */#elif defined(_MSC_VER)/* Microsoft Visual Studio. --------------------------------- */#elif defined(__PGI)/* Portland Group PGCC/PGCPP. ------------------------------- */#elif defined(__SUNPRO_C) || defined(__SUNPRO_CC)/* Oracle Solaris Studio. ----------------------------------- */#endif
