Can you also state the version number of libgcc2.c? I'd like to look 
at the actual line, the error message strikes me as rather badly 
worded...

> Can you also state the version number of libgcc2.c?

Its the version from gcc-HEAD (gcc version 4.0.0 20040928)
The error-text seems to come from varasm.c :-/

I can't reproduce this error message on x86 linux with your .i file 
and a CVS snapshot of an hour ago :-(

Confirmed:

The problem comes from:
2011      /* Avoid GAS bugs for values > word size.  */
2012      if (size > UNITS_PER_WORD)
2013        return false;

Caused by:
2004-09-21  Paul Brook  <paul@codesourcery.com>
        
        * varasm.c (default_assemble_integer): Return false for values wider
        than the target word size.  Works around GAS bug.


Reduced testcase:
typedef void (*func_ptr) (void);
extern func_ptr __DTOR_LIST__[];
func_ptr *p = __DTOR_LIST__ + 1;

Still present on mainline.  Prevents bootstrap on avr.
