1. Ansifront-0.12 is a given.  It converts a huge percentage of ansi-c src 
code into something digestible by the rest of the compiler.

2. My cprep19 is another unless your srcs never go over 8 or 9k.
Basicly, if your code compiles but crashes, use my cprep, its been tested 
with sources to nearly 40k.

3 cc drivers, including our old 'make' or any of the scripts are up to the 
user. All can do the job if run correctly.

4. cc1->cc2 can be used, or there are copies of cc itself about, usable only 
an a coco3 with more memory.  No particular speed advantage to the one piece 
version if using a ramdisk for scratchpad.  Results at the output are 
identical. Assembly code, code that may just show you a trick or 2 if just 
learning assembly.  Its also a good place to stop the build, plug in your own 
tricks, and then continue with the assembly and linking.

5 there is an extra c.opt2 about that can help a wee bit.

6. There is, only for coco3, a "CnoY" utility that removes y register use as 
its a cycle longer to use, a minor speedup in the object.

7. There must now be at least 3 or 4 versions of its 'rma', relocating macro 
assembler, and I believe matching versions of r.link, which takes the 
assembled code, and links in the library routines to make a complete, 
standalone executable binary.  The idea between 4 and here, is that if you do 
come massaging of the assembly code to optimize it better for the h6309, then 
you will also need the later versions of rma that understand 6309 nemonics, 
and I believe for the linker used.

8. The std clib.l (??name) should probably be replaced with Karl Kreiders 
version, more accurate, and more optimized.

9. For trig usage, there is the trig.l that was built from code published, 
somewhat sloppily IMO, in the rainbow long ago.  I had a heck of a time 
telling the diffs between the character one '1', and the letter el 'l' as 
shown by the font and dmp printer output used to make the plates that printed 
the rainbow.  It only works right when you get it right.  And gives answers 
accurate to 1.0ee+-16 or 17 digits, that is a few digits more accurate than 
the other languages we have.

There is probably more, but that is a general outline.
