State-Changed-Why:
    It's not a bug - the class layout in the testcase is not
    the one it's supposed to be (but yet it should be documented
    better), changing it to be the required one fixes the problem

Please see minimized testcase bug1.m:

$ gcc -v
Reading specs from /home/daa/bin/../lib/gcc-lib/i686-pc-linux-gnu/3.1/specs
Configured with: ./configure  : (reconfigured) ./configure
Thread model: single
gcc version 3.1
$ gcc bug1.m -fconstant-string-class=NSConstantString -lobjc
bug1.m:1:2: warning: #import is obsolete, use an #ifndef wrapper in the header f
ile
/tmp/cciVxsfG.o(.data+0x280): relocation truncated to fit: R_386_16 .rodata
collect2: ld returned 1 exit status

There is workaround for this :

$ gcc bug.m -fconstant-string-class=NSConstantString -lobjc -DFIX
bug1.m:1:2: warning: #import is obsolete, use an #ifndef
