Note that the minimum version of "Visual Studio 2017" is not "any old Visual Studio 2017" because I just tripped over that. The cmake configuration wants version 19.1 or later, so 19.0 is not sufficient. --paulr

Hello compiler fans!
As discussed in the RFC<http://lists.llvm.org/pipermail/llvm-dev/2019-January/129452.html>, LLVM’s cmake configuration now soft-errors if you use an older toolchain to build. The new minimums are:
- Clang 3.5
- Apple Clang 6.0
- GCC 5.1
- Visual Studio 2017
You can opt-out of the soft-error with LLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN. You’ll still want to update your toolchain because that soft-error will become a hard-error once we move away from C++11, and we would truly miss you. I will send another RFC for this migration away from C++11 at the end of March 2019.
Happy compiling!
