 I can't make any sense of it and I can't reproduce this by doing "make
clean" followed by "make install" neither. I didn't run the full
install_msw.sh because it takes a rather long time, but I could it, of
course, it's just that I don't see how could it explain the problem and so
even if it did allow me to reproduce the problem, I'm not sure it would
help me to understand it.

 I know it's a cop out, but could it have been just a random fluke (not
sure if cosmic rays are more or less likely on the eclipse days)? Or is it
reproducible in your case and, if so, is it enough to run "make clean" to
see it happen again or not?
