    Record speed measurements [terque]
    
    These measurements use gcc-10 for all architectures, and wine-4.0.3
    (wine four, not five). Compared to commit 641831ad4:
      - i686-w64-mingw32 is thirty percent faster for the no-solves
          scenario, and forty to fifty percent faster for other scenarios
      - x86_64-pc-linux-gnu is about the same--maybe one percent faster
      - x86_64-w64-mingw32 is about one percent slower
    If the effect of std::filesystem isn't much, then gcc-10 would seem
    to have made an enormous different for i686 with wine, and to have
    eliminated most of the x86_64-w64-mingw32 vs. i686-w64-mingw32
    advantage; it would be interesting to learn whether that happens with
    native msw.
