L. Peter Deutsch,

I have installed Ghostscript 2.5.2 (9/20/92) on our IBM RS/6000 running
AIX 3.2 with MIT X11R5 and IBM cc/c89/xlc 1.02.  There are two small bugs.

1) The identifier op_def_table is declared in both "opdef.h:74" and
   "iinit.c:59".  `c89' gives a severe error, but `cc' compiles.  See below.

2) AIX has a well-known bug where the function DisplayWidthMM() gives
   absurd values for some Xstations with hardware panning.  Thus, I set
   the following resource:
	Ghostscript*xResolution:        91
   However, this was ignored unless I also had:
	Ghostscript*yResolution:        91
   This is because of the logic in gdevxini.c function gdev_x_open.
   I think it only uses the resources if both are defined.  See below.
   Perhaps it should have this kind of structure:

	if ( x_res_str )
	  x_res = atof(x_res_str);
	else
	  { ...
	  }
	if ( y_res_str )
	  y_res = atof(y_res_str);
	else
	  { ...
	  }

Thank you,
