Hi,

This patch fixes the warning:
...
terminals.c:1266:21: warning: argument to ‘sizeof’ in ‘bzero’ call is the same 
expression as the destination; did you mean to remove the addressof? 
[-Wsizeof-pointer-memaccess]
...

bootstrapped and reg-tested on x86_64.

OK for stage 4/stage1?

Thanks,
- Tom
