PatR 171fb90746 !DEBUG warnings 
With DEBUG suppressed, I started getting
16      warning: empty body in an if-statement
and 2   warning: empty body in an else-statement
from gcc.

Using braces for an empty block instead of just ';' avoids the warning:
    if (foo)
        debugpline("foo");
is bad,
    if (bar) {
        debugpline("bar");
    }
is good.  ;-)

The changes to lint.h are just precautionary.
