The problem is that troff font width files (apparently) do not have
same formats in BSD and System V. System V troff font width files
do not have any fileheaders preceding the actual information.

The following patches made troff2lj work on a 3B2/600
running Unix System V release 3.1.1. 

Apply only if you're running System V. Then recompile dewidth.c
with -DSYSV

ccfinfo:
In System V, you can't strip a relocatable object, so use the count
option in dd instead. Sizeof(struct hpfontinfo) may be 5, 6 or 8
on your system, but assuming 8 will work on any system (I think).

dewidth.c:
when compiled with -DSYSV, dewidth will correctly calculate the
the size of the object file header. This will now only be used
for dewidth -h, as hdrb will be set to 0 when decompiling
a font width table.

htroff:
htroff should call otroff, as troff is the device indepent troff
and otroff is the C/A/T troff.
