Since the NetBSD/m68k code hadn't been updated for a while I didn't re-use any of the old code. However, the new code was written with sharing the code between OpenBSD and NetBSD in mind, so used the neutral names m68kbsd-nat.c and m68kbsd-tdep.c for the new code. Attached you find a patch that modernizes the NetBSD/m68k by using that new code. I've axed the signal trampoline recognition code; it would only recognize on-stack signal trampolines and would therefore be useless for NetBSD 2.0. The old stuff didn't compile anyway on NetBSD/mac68k 1.6.2. The new stuff adds cross-debug support and support for ELF. Do you have any objections if I check this in, and make some further imporvements towards properly supporting signal trampolines?
