Sure, if you are not doing that, you'll have all sorts of problems.

Also, you mentioned that SDS does not support gcc's -g feature, so you
are debugging assembly code.  I'm using gcc-2.95.2, binutils-2.91, and
newlib-1.8.2 with the SDS 7.5 debugger, and it works fine (MPC8xx
processor).  The debugger understands the elf output file and I can
debug c source code (haven't tried c++).
