I now have the results for Aztec C II Vers. 1.05h 6502  (C) 1982, 1983 by 
Manx Software Systems MS-DOS (Windows XP) Cross-Compiler running in WinVICE 
Version 1.22 at 41 DHRYSTONES/SEC .

This is already faster than Commodore 64 6510-1MHz C64 ROM  C Power 2.8  at 
36 DHRYSTONES/SEC  by 13%.

I will be posting a complete working program with d64 disk image to the 
Aztec C Website in the next few hours. If WinVice can be believed, the C64 
results for Aztec C II  are 4 DHRYSTONES/SEC over the older Apple IIe 
65C02-1.02Mhz DOS 3.3  Aztec CII v1.05i equivalent compiler  which achieved 
37 DHRYSTONES/SEC (2 DHRYSTONES/SEC slower than the newer version 3.2b 
achieved.) I will confirm this (in time of course), but if the same CII 
compiler is 10% slower on the Apple II than the C64, that may also hold true 
with the cc65 compiler on the Apple II.

I am speculating at this point because as I say I have no stats for cc65 for 
the Apple II (just for the C64) but if my theory is correct, and the same 
ratio of 37 Apple II to 41 C64 applies to cc65, then cc65 should come-in at 
45 DHRYSTONES/SEC on the Apple II as opposed to Aztec C65 3.2b's 39 
DHRYSTONES/SEC. I'll need to leave it to the cc65 people to sort that one 
out. There was some comment about optimizations as well (see link above), 
and the fact that 5 points may be lost without them which may even bring 
cc65 down to 40 DHRYSTONES/SEC on the Apple II (again speculating). Without 
verifiable results it's hard to tell. What version of DHRY was that 
anyway???

Considering that Aztec C65 also offers floating point support and inline 
assembly, and the ability to read files in DOS 3.3, as well as the ability 
to create command line programs for its unix-like shells for both DOS 3.3 
and ProDOS...

So as it stands now, the older Aztec C for the Commodore 64 which also 
provides floating point support and well-documented overlays etc. still 
achieves 82% DHRYSTONES/SEC of cc65 posted results on the C64 (not sure 
about that 5 point business either) so it may be closer to 91%. I wonder too 
if I will achieve better results with the C64 when I complete my port to the 
newer Aztec CG65 3.2c compiler from Paul Santa-Maria?

I also found it interesting that even though I have absolutely no problems 
compiling DHRY for Aztec C for the C64:

http://www.cc65.org/mailarchive/2009-10/7171.html

It's a poor workman that blames his tools.

BTW, there won't be any cc65 results from me.... I've got my hands-full with 
Aztec C.  And Aztec C's documentation is too complete, and its environment 
too feature rich for me to bother with something else on the Apple II after 
using Aztec C for such a long time with good results.

I don't stumble through documentation either; I take time to read it. I must 
be getting old, because I feel like saying "If it was good enough for 
Grandpa, it's good enough for me". As for memcpy, I guess I could have used 
the Aztec C equivalent but didn't need it. I used an appropriate version of 
DHRY...
