I can't find any clang installers. Do you mean the 263 MB installer of 
the whole LLVM 
(https://github.com/llvm/llvm-project/releases/download/llvmorg-14.0.5/LLVM-14.0.5-win32.exe 
or 
https://github.com/llvm/llvm-project/releases/download/llvmorg-14.0.5/LLVM-14.0.5-win64.exe)? 
Moreover, that wouldn't provide the executable aarch64-win64-clang.exe 
expected by FPC, would it (unlike the contributed cross binutils 
provided by Pierre and some others for other architectures)? I believe 
that we should either reconsider the idea of not providing such binaries 
ourselves, or change the compiler so that it can invoke the tools as 
installed by the installer (or to provide detailed steps necessary for 
making this to work as the very least, but my personal opinion is that 
this last option wouldn't be the right thing to do in this case).
