  I got those too.  I avoided the warnings by using "0.999n" instead of
"1n" in one of the arguments of "TBL".  The cause is thus most probably
a rounding error, so a better solution is to apply a correction where
the rounding error occurs.

  There is still a fix (explanation) missing for the empty parentheses
in the warnings.

I avoided the ".pso" warning by adding "-U" to the HDTBL_PFLAG.

Then I did not get the other warnings, but the "fonts_n.ps" file does
not show any font, while "fonts_x.ps" contains all of them (38).

  An older "fonts_n.ps" file shows only the first font.
