If you omit compiler-rt, does it work? (compiler-rt is not a required
component.)

For the most part, LLVM works fine on Windows, with some limitations.
Clang has serious shortcomings, more so if you build it with VS (Mingw
is better because Clang can use the headers and standard C++ library
that comes with MinGW, but not the standard C++ library that comes with
VS.)

Yes. What you are seeing are the platform checks, where the build system
looks for the presence of functions, headers, etc and then generates a
configuration file with that information.

Thanks for your reply.

Compiler-rt was a problem. From the documentation I thought it was 
mandatory (so what is it used for?),

but it was giving all those error about stdbool.h missing that I reported.

Now things got better, but I have still problems.

I receive an error that seems related to the fact that the grep command 
is missing.

Is it possible? If grep is needed, how can I found it in Windows?

Thanks in advance,
   Giorgio

See here:

grep (and a few other required tools) are in the GnuWin32 tools.
