1.65.1 with some stuff from develop that allows boost to be compiled with
std=c++17 using vc15.4.

I tried many things, but in some of those trials <ranlib>"C:/Program
Files/LLVM/bin/llvm-ranlib.exe"  <archiver>"C:/Program
Files/LLVM/bin/llvm-ar.exe" being not defined was causing trouble, so I am
gonna give that a try and get back how it went.

You could give the latest snapshot build <http://llvm.org/builds/> a try
with <linkflags>-flto=thin added and see what it brings for you. It seems
impossible to build your app from the VS IDE though (the passing of
-flto=thin doesn't work somehow), but from the command line it gives
exellent results.

I would like to thank you for your post.
