Just tried to use the patch that you so kindly pointed me to, and 
received the following:

Hmmm...Looks like a new style context diff to me...
The text leading up to this was:
-------------------------
|RCS File: RCS/macdep.c,v

Patching file machdep.c using Plan A...
patch: ****unexpected end of file in patch

The actual patch is as follows (Hopefully the formatting will come 
through)

I have as I said, never tried to patch anything before and have the patch 
named "mh_patch" (I am assuming the name doesn't matter here) and is 
located in /  so the command line I used was (from the directory 
/src/sys/arch/mac68k/mac68k)

% patch < /mh_patch

the machdep.c file was in the same directory that I was in 
(/src/sys/arch/mac68k/mac68k) so I am wondering where I went wrong 
here...  ;)  Please gimme some more advice :)

Greg
