[Coco] Compiling NitrOS9.

[Phill Harvey-Smith]

Hi all,

I's been a while since I tried to compile Nitros9, and as I wanted to 
develop a drive for DragonMMC, I decided to get the source and do a 
trial build to make sure things still worked.....

I'm working on cygwin under Windows 7 x64. Though before when I worked 
on this I had all the tools on Linux, so willing to try that too.

So I went and go the NOS9 source from sorceforge along with toolshed and 
lwasm. I have compiled the lwasm sources (4.16) under cygwin and 
installed them. (make / make install).

However when I try to build nos9, by changing into it's directory and 
typing make from my cygwin bash prompt, ig builds part of it and then 
craps out compiling edit.asm :

lwasm --6309 --format=os9 
--pragma=pcaspcr,nosymbolcase,condundefzero,undefextern,dollarnotlocal 
--includedir=. 
--includedir=/cygdrive/e/retro/Dragon/nos9/nitros9-v3.3.0/defs

Plus a load more instances of the bad register message which is 
understandable as you generally can't push a stack register onto itself.....

Any hints much appreciated, including...this is the wrong place you 
should ask on some other list / forum :)

Cheers.

Phill.
