In the x06f.f file, after m4 processing, appears indeed a very long line =
as=20
the first fortran source line:

! Displays the plotter=20

      integer i, j, k
      real*4 x, y

      character*3 text

! Full sized page for display

So it seems that this is a m4 problem. But suse-7.2 is not that old, and =
my=20
suse system is updated with the last changes... (rpm says that m4 was "Bu=
ild=20
Date: Fri 11 May 2001")

The problem seem to be the word "symbols" in the comments and in the last=
=20
plmtex() arguments of file x06f.fm4; if I remove the word "symbols" from =
the=20
comments, the lines will be no more expanded by m4 as above. What is the =
real=20
cure for this?
