Interesting. I also did a standard build and still see an horizontal
offset (and the XXX printf). Is Ubuntu 12.04's version of Times New
Roman just too old? IIUC, "sudo apt-get install
ttf-mscorefonts-installer" downloads the fonts from
http://sourceforge.net/projects/corefonts/files/the%20fonts/final/ and
the timestamps on that page say 2002-08-15. Grepping the times.ttx
file gives "Version 2.82". Is this ldot thing essentially a font bug
that was fixed (but not in Ubuntu's older version)?

Let me know if you want the /tmp/x.configure or /tmp/x.make{1,2} files.
