  I've already changed my local copy of ps.c. It compiles without 
error.  Below is the abbreviated text I actually used:

Starting at line 1390 in pcb/src/hid/ps/ps.c:

  "\n",
  "(Please measure between the flat faces of ONE pair of semi-circles 
on)t\n",
   "(both X and Y in the indicated units. Enter these values as X and 
Y)t\n",
   "(respectively. One member of each pair must be one of the 
semicircles)t\n",
   "(in the lower left corner. Nominal lengths on X are 4 in, 15 cm and 
7.5 in.)t\n",
   "(Nominal lengths on Y are 4 in, 20 cm and 10 in.)t\n",
   "()t\n",
   "(The large box is 10.25 by 7.75 inches and is not used for 
calibration.)t\n",

This is part of the definition of static const char * const 
calib_lines[], which starts at line 1329.
I also tried to add nominal values to the Y in, Y cm, X in and X cm 
labels. This more or less worked, so that I now
I have something like "Y cm nom=20" on the Y axis. Howeer, since the 
text is rotated on X, the nom= part gets
clipped. I am not sure how to fix this. Perhaps someone has a 
suggestion.  Here is the code (from void ps_calibrate (...:

   fprintf (ps_cal_file, "4 in 0.5 (Y in nom=4) cbar\n");
   fprintf (ps_cal_file, "20 cm 1.5 (Y cm nom=20) cbar\n");
   fprintf (ps_cal_file, "10 in 2.5 (Y in nom=10) cbar\n");
   fprintf (ps_cal_file, "-90 rotate\n");
   fprintf (ps_cal_file, "4 in -0.5 (X in nom=4) cbar\n");
   fprintf (ps_cal_file, "15 cm -1.5 (X cm nom=15) cbar\n");
   fprintf (ps_cal_file, "7.5 in -2.5 (X in nom=7.5) cbar\n");

Since I don't have commit rights, I will leave it up to someone who does 
to move this into the code base.
