This will be used to support conditional compilation based on compiler version. We adopt the same convention as [libc++](https://github.com/llvm/llvm-project/blob/main/libcxx/include/__config) - thx @legrosbuffle for the suggestion! Usage: ``` #if defined(LIBC_COMPILER_CLANG_VER) # if LIBC_COMPILER_CLANG_VER < 1500 # warning "Libc only supports Clang 15 and later" # endif #elif defined(LIBC_COMPILER_GCC_VER) # if LIBC_COMPILER_GCC_VER < 1500 # warning "Libc only supports GCC 15 and later" # endif #elif defined(LIBC_COMPILER_MSC_VER) # if LIBC_COMPILER_MSC_VER < 1930 # warning "Libc only supports Visual Studio 2022 RTW (17.0) and later" # endif #endif ```
