Looks like this was always broken, it just required some extra configure
argument.
I would "drop this thing" or, better, you could compile with
"--enable-trace-backend=nop" on the old mingw setup and without it on
the new one. This has the additional advantage of better coverage.
We should also add -Werror=format to the Makefile.
