a2ps display wrong intrinsic function names

[Luc Maisonobe]

Hello,

We have found a funny bug in a2ps 4.12 while trying to display the
following fortran file :

      double precision function gasp (y, x)
      double precision y, x
      gasp = atan2 (y, x)
      return

The following command line works well :

   a2ps -P display --highlight-level=none gasp.f

However, when we try to use the pretty-printing features, the atan2
intrinsic function is shown as cabs !

   a2ps -P display --highlight-level=normal gasp.f
