Since roughly one day ago some BISTs are failing on Windows for me:

The two tests don't look related. But they started failing with the same
build. (That might be incidental.)

I was building with local changes that are stripped now. So, I can only give a
rough range.
Last good: build from 5th of April (MXE hg id 05703685a4a8, Octave hg id
unknown)
First bad: build from 6th of April

I built from the default MXE branch. IIRC, the update of lapack, lua and curl
falls into that range.
I don't remember which revisions my local changes in Octave were based on.

I did incremental builds. I'll check if the errors disappear with a clean
build.
