Which libc are you using?

# nm /lib/libc-2.0.7.so | grep __deregister_frame_info
0008ba58 T __deregister_frame_info
# objdump --dynamic-sym /usr/bin/gcc | grep __deregister_frame_info
08048ca4      DF *UND*  000000a8 __deregister_frame_info

You should use the latest glibc 2.0/2.1 from CVS and compile it with
egcs 1.1.1/Linux.

Please don't change anything to glibc/egcs before Ulrich andd I
take a look at the proposed the change.
