I compiled the following two programs on a 3B2-400 Sys V.3.2

main()               main()
{ int a,b;           { int a,b;
  !(a>b);              a<=b;
}                    }

cc -S foo.c          cc -S foo2.c

This is the diff:

1c1
< 	.file	"foo.c"
---
> 	.file	"foo2.c"

Accucally, I was a bit surprised. Perhaps other compliers produce
something different?

If something is worth doing, it's worth doing correctly.
