Thank you for your answer.  However, I just did it by hand and the result was the same.  I think I did it by hand for my original example, too, and not using the Makefile.

dvipdfmx -r 300 ttemp.dvi # (output attached)

On my system, the two PDF files are different with the version from dvipdfmx having the font at half the size.
