Yes. Your problem being ? :)) 

Given it worked when I compiled it, that's enough QA for participation in
this thread I feel ;)

Having thought about this a bit now, I want to start grepping through code
for examples in the wild :) Theoretically, gcc could optimize the above
statement to 0 pretty easily, I wonder if it does...

[Playing with gcc:

	movb $0,-8(%ebp)

eek! it _does_ optimize it to x[0]=0!!]

Cheers,

Alex.
