--- Comment #2 from John Paul Adrian Glaubitz <glaubitz at physik dot fu-berlin.de> --- A local native bootstrap went through without problems, so maybe it's a problem with the Debian buildds. I'll try to track it down and if I can reproduce it locally, I will provide the preprocessed source, of course.
