 Notice that clang also defines the GNU C version macros, but you should use the clang [feature checking macros](http://clang.llvm.org/docs/LanguageExtensions.html#feature_check) to detect the availability of various features.

 The values of the `__clang_major__`, `__clang_minor__`, and `__clang_patchlevel__` macros are not consistent across distributions of the Clang compiler.  For example, the Clang 3.1 distribution available at http://clang.llvm.org defines `__clang_major__` and `__clang_minor__` as `3` and `1` respectively.  The version of Clang distributed with Apple XCode 4.4 is branded as "Apple Clang 4.0" and derives from the open source Clang 3.1 distribution, but defines these macros with the values `4` and `0` respectively.  Apple's Clang distribution can be identified by the presence of the `__apple_build_version__` macro.
+
+The meaning of the `__clang__` and related macros has changed subtly over the years, from identifying the Clang compiler to identifying compilers that use the Clang infrastructure. For example, IBM XL C/C++ also defines these macros. [IBM XL C/C++ for Linux](https://www.ibm.com/support/knowledgecenter/en/SSXVZZ_16.1.1/com.ibm.xlcpp1611.lelinux.doc/compiler_ref/xlmacros.html?sc=SSXVZZ_latest) defines them starting from version 13.1.1. [IBM XL C/C++ for AIX](https://www.ibm.com/support/knowledgecenter/en/SSGH3R_16.1.0/com.ibm.xlcpp161.aix.doc/compiler_ref/xlmacros.html?sc=SSGH3R_latest) defines them starting from version 16.1.

+The Clang compiler has an expectation that it operates in conjunction with the LLVM compiler, so the Clang compiler defines `__llvm__` too. IBM XL C/C++ (Clang-based versions) use Clang infrastructure, so IBM XL C/C++ for Linux versions 13.1.1 to 16.1 also define `__llvm__`. Starting from version 16.1.1, [IBM XL C/C++ for Linux](https://www.ibm.com/support/knowledgecenter/en/SSXVZZ_16.1.1/com.ibm.xlcpp1611.lelinux.doc/compiler_ref/xlmacros.html?sc=SSXVZZ_latest) no longer defines `__llvm__`.
