	I finaly got XPS (Crispin Goswell's postscript previewer) to work
successfuly on an IBM RT/PC. Sorry I do not have a context diff, I don't
have room to keep the originals.

	First of all use hc1.4 with the -O option. hc1.4 is included
on AOS R2 if you have AOS R1 use hc. You need to change the variable
"signed" in integer.c, I called it isigned. Make sure Malloc calls
malloc in save.c, do not use the small_buff. Finaly make the following change
to "mat.h":

Change:

	typedef struct vector {float vx, vy, vt;} Vector;

To:

	typedef struct vector {float vx, vy, vt, foo;} Vector;


	Changing the Vector type will allow fonts to be spaced. Why
the HC compiler likes even number of fields when returning structures
from a function I'll never know! I have not tried the speedups yet,
maybe the next week or two. I'm realy getting the hang of the HC
compiler bugs now. HC is realy a plot to sell AIX!!!!!!
