Yay, Outcome now runs its unit tests and all pass (well, except one on my version of MSVC, which has a compiler bug). Thanks to Rene for the timely fix to Predef and to Michael for holding up the release to get this fixed. Niall

I tried to build it on Ubuntu 18.04 with GCC 8 and C++17, with support for LibICU enabled, and got the following error: ``` error: Name clash for '
