This looks reasonable now, thanks.  I still think, however, that the
difference is mainly due to the redirection.  Theoretically,
`FT_LOGGING` should be a tiny bit slower than `FT_DEBUG_LEVEL_TRACE`
since the former has a larger overhead.

What do your GNU/Linux tests show?

Alas, I don't use Windows so I can't check this.
