Re: [avr-libc-dev] [bug #28108] bug with winavr20090313

[Szikra Istvan]

Hi all!

"Good" to see this bug again. I reported it at 2009-03-30 as
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39593 .
Later it turned out to be a duplicate report of #37466 which was
marked fixed at 2008-09-12.
Interestingly WinAVR-20090313 still had tis bug (gcc 4.3.2)
good times :)

I just compiled my testcase (attached to #39593) with WinAVR-20100110
(gcc 4.3.3) and it seems OK. (If anyone still interested)

Sorry for replying to an old message.

By the way anyone knows why WinAVR is lagging behind gcc version?
If I'm not mistaken GCC 4.3.4 was released 2009-08-04, and 4.4.2 at 2009-10-15.
GCC 4.3.3 was released 2009-01-24 before WinAVR20090313 and it would
have been nice not to run into already fixed bugs...
Or maybe there's a tutorial how to compile your own winavr build with
latest gcc, binutils, libc?
(Something like http://www.devside.net/guides/windows/apache for Apache build)
