I was going to try compiling ARC with Sozobon, to see if it would
produce any smaller/faster code than MWC, but I think I'm going to
abandon that idea now. The preprocessor won't handle boolean expressions
on #if lines correctly. e.g.
	#if MACRO1 || MACRO2

generates the message "must be constant" or something to that effect.
It *really* doesn't like using an #undef'ed name either. My copy of K&R
doesn't really say very much about what the preprocessor is supposed to
do in those situations, so I guess it's more a problem for me, not a bug.

In any case, I guess I'm stuck with MWC until Turbo comes along, or maybe
if I can get decent library routines for GCC. 

I just ordered and received the source code for the MWC library. Pretty
handy to have, since there seem to be some useful functions there that
I can't find anywhere in my 2.00 Lexicon, nor the 2.1 and 3.0.6 update
pages... Interesting to note that the library sources say they're for
3.0.9, but I've only heard of a 3.0.6 in their 3.0 release... Ah well.

Added a Unix-style setbuffer() to the stdio lib, using a 30K file buffer
in ARC seems to speed up ARC'ing on floppies by about 30%, for large files.
Not a bad gain for such a cheap addition... (But figure it at up to 90K
more memory required, when adding files to an existing archive it needs
at least 3 buffers.)
