Hi Eric.

Is there any chance that GCC 4.3.1, about to be released around 
05/05/08, will include the patches you have included in WinAvr?

Currently if one does not read all the traffic on this mailing list, 
it's difficult to know what patches are required to have a fully 
fonctionnal avr-gcc toolchain.

When reading  http://www.nongnu.org/avr-libc/bugs.html , one may even 
think that GCC 4.3.0 fixes a lot of things and that this is the version 
to get since many bugs are listed as 'fixed in >=4.3.0' or even 'Fixed 
in 4.3-20070525.' !

I'd like to upgrade my toolchain on Linux, and if I read the list 
correctly, the surest solution is first to get WinAvr 20080411, grab the 
included patches and apply them to stock FSF source code to be able to 
have, at last, a working Linux toolchain. (Linux needing files first 
released for Windows... arg!)

IMHO it is difficult today to know exactly what files are needed to have 
a working toolchain, compared to a few years ago when reading 
http://www.nongnu.org/avr-libc/user-manual/install_tools.html was 
enough: this page was all I read when I started using avr-gcc and I was 
happy with the result.

If one reads this page today and try to follow it to build the 
toolchain, then the result will be a disappointment because of the 
current 'patch mess'.

Could the exact list of files/patches to use be listed somewhere on 
http://www.nongnu.org/avr-libc website?

Or will the release of 4.3.1 fix everything?

Thanks!
