The eqnrc is inserted by eqn, but in the pipeline run by
"groff -e -p", eqn runs *after* pic, so pic never sees this input
and cannot act upon it.  Since pic does not (as far as I know)
have an analogous automatic startup file, you have to move the
pic stuff out of the eqnrc and into a "picrc" that you must
include manually:

  groff -e -p picrc test.groff >test.ps
