--- Comment #3 from nightstrike <nightstrike at gmail dot com> --- Hm, looks like it *IS* in 11. I was confused by the PR being open and the version stating 11, thinking that it still wasn't applied. So the remaining issues then are building on cygwin. But at least on a linux to mingw cross, the testsuite passes with only 33 fails.
