or the command line to the linker is wrong. Here it is:

/users/joel/test-gcc/b-gcc1-m68k/gcc/xgcc 
-B/users/joel/test-gcc/b-gcc1-m68k/gcc/ 
/users/joel/test-gcc/gcc-svn/gcc/testsuite/gcc.c-torture/execute/zero-struct-2.c 
gcc_tg.o  -w  -O2 -fwhopr  -DSTACK_SIZE=2048  -isystem 
/users/joel/test-gcc/b-gcc1-m68k/m68k-rtems4.10/./newlib/targ-include 
-isystem /users/joel/test-gcc/gcc-svn/newlib/libc/include 
-B/users/joel/test-gcc/install-svn/m68k-rtems4.10/uC5282/lib/ -specs 
bsp_specs -qrtems -mcpu=5282 
-B/users/joel/test-gcc/b-gcc1-m68k/m68k-rtems4.10/./newlib/ 
-L/users/joel/test-gcc/b-gcc1-m68k/m68k-rtems4.10/./newlib 
/users/joel/test-gcc/b-gcc1-m68k/rtems_gcc_main.o  -Wl,-wrap,exit 
-Wl,-wrap,_exit -Wl,-wrap,main -Wl,-wrap,abort -lm   -o 
/users/joel/test-gcc/b-gcc1-m68k/gcc/testsuite/gcc/zero-struct-2.x7

Notice the "-L/users/joel/test-gcc/b-gcc1-m68k/m68k-rtems4.10/./newlib" 
path. I think this may be the source of the problem.
