This unbreaks the build of most consumers, except games/witchblast.
The FreeBSD patch is partly responsible:

Causes:

/usr/local/include/SFML/System/String.hpp:69:9: error: statement not allowed in constexpr functio
n
   69 |         for (; count; --count, ++lhs, ++rhs)
      |         ^


This subsequent error indicates that there's more to fix in String.hpp:
