Hi; this generates a new warning on the NetBSD build:

../src/bsd-user/main.c: In function 'cpu_loop':
../src/bsd-user/main.c:513:16: warning: this statement may fall
through [-Wimplicit-fallthrough=]
             if (bsd_type != target_freebsd)
                ^
../src/bsd-user/main.c:515:9: note: here
         case 0x100:
         ^~~~
