[avr-gcc-list] General tips on patching gcc?

[Rick Mann]

Hi. I have 3 main questions:

a) I think I found the patches I need to support the at90usbxxx  
parts. Is this right?

http://gcc.gnu.org/ml/gcc-patches/2006-05/msg01001.html

b) The email referenced above has a subject prefixed with [AVR][4.2].  
As far as I know, the latest release of gcc is 4.1.1. Is the "4.2" in  
the subject referring to gcc version 4.2.x? Is there a similar patch  
for 4.1.x? Is 4.2.x good enough for regular AVR development work?

c) I'm thinking of making a downloadable binary package installer for  
Mac OS X, and I'd like to automate the process of building the tools  
as much as possible, so that I can easily provide current versions of  
the AVR toolchain. What's the best way to stay abreast of the  
releases and appropriate patches for AVR-targeted gcc? (I can handle  
automating the local builds and Mac OS X-packaging, I think.)

Thanks!
