Be careful with the frame pointer. On X86, for example, it is used to
process exceptions in C++ programs. I don't know how it behaves in this
case on m68k. Also, yesterday I add a problem with gcc 2.95 on m68k, and
a program dealing with 64 bits integer. long long values where stored in
the stack frame, link/unlk instructions where used, even if I add
-fomit-frame-pointer.

The best thing you can do, is try to run gdb on a program compiled
without the frame pointer.
