 This is still broken in current's gdb 7 on amd64, although it's less
 obvious because "NetBSD a.out" isn't one of the choices.
 
 Plus maybe there's another problem:
 
 (gdb) set osabi NetBSD ELF
 warning: A handler for the OS ABI "NetBSD ELF" is not built into this 
configuration
 of GDB.  Attempting to continue with the default i386 settings.
 (gdb) 
 
 (gdb) set osabi NetBSD fail
 warning: A handler for the OS ABI "NetBSD ELF" is not built into this 
configuration
 of GDB.  Attempting to continue with the default i386 settings.
 (gdb) 
 
 I'm not sure to what extent this warning really matters.
