This one is also a fault: do { } while(0) is added to a set of
statements to make it appear to the compiler as a unit. If you add an
extra semicolon at the end you get a hidden double semicolon which can
lead to unexpected problems. For instance
for (SNIC_TRC(...), i=1; ...)
will cause an error.
I fixed this up too.
