Sent privately... wanted to log this .. untested at this point.
Please excuse me, I could not reply earlier.
Use patch for binutils:

The binutils patch mentioned in comment#2 seems to fix this issue.
Today's gcc-trunk using binutils-2.18 with the patch applied doesn't expose
this breakdown anymore.
=> The cause for this breakdown was using insufficient binutils.
Bootstrapping/building gcc-4.3 for the avr requires binutils > 2.18.

------- Comment #5 from Rudolf dot Leitgeb at gmx dot at 2008-02-11 17:48 -------
Subject: Re: illegal opcode movw for mcu avr3
Please note, that this bug is also apparent in the production
version of gcc 4.2.3. This is the specific reason why I posted
a supposed copy of the original bug report: the original bug
report mentioned version 4.3, and I was unable to add version 4.2.3
to the list of affected gcc releases.
Hopefully I can get around to try out the patch tonight. Please
note that while it's perfectly acceptable for a snapshot release
like gcc 4.3 to require patched binutils, this should not happen
for a standard release version of gcc IMHO. AFAIK there is no
binutils production release newer than 2.18 at the moment.
Cheers,
Rudi

------- Comment #6 from Rudolf dot Leitgeb at gmx dot at 2008-02-11 19:25 -------
I just tried the suggested patch against binutils 2.18, gcc 4.2.3 still does
not compile. Also, the suggested patch does not apply cleanly against 2.18,
although this only affects a .texi file which is not needed for compilation. It
does indicate, though, that the patch wa snot meant for binutils 2.18 but some
preversion of binutils 2.19 instead.
I hope this new version comes of binutils out soon, since 2.18 doesn't know of
a platform avr35 :-( Hence gcc 4.2.3 uses avr3 which causes touble.
Note: I don't fully understand why the patch doesn't work. I clearly see a line
which defines the AVR3 platform to support MOVW, I did a make clean && make &&
make install of the manually patched binutils before trying gcc again (also
with make clean && configure --target=avr && make)
Maybe I have to wait for binutils 2.19 before this gets cleared up ...

You can also try the patch set for binutils 2.18 at the WinAVR project's CVS:
<http://winavr.cvs.sourceforge.net/winavr/>. Under the "patches" module.
