As far as I know, libm.so in glibc 2.0.7 still exports register_frame:
# nm glibc-2.0/math/libm.so | grep frame
00014500 T __deregister_frame
00014458 T __deregister_frame_info
00014528 T __frame_state_for
0001438c T __register_frame
00014314 T __register_frame_info
000143b8 T __register_frame_info_table
0001442c T __register_frame_table
000046a0 t frame_dummy
00013c98 t frame_init
Ulrich, can you comment on that? BTW, I am using egcs 1.1.1.
