2. trigger.c fails to compile due to a syntax error. It contains

    a switch statement that has an empty default label.  A label of a
    switch statement must be followed by a statement (or a label which
    is followed by a statement (or a label which ...)).

3.  Files include stringinfo.h failed to compile.  The macro,
    'appendStringInfoCharMacro' is implemented with a '?:' operation
    that returns a void expression for the true part and a char expresion
    for the false part.  Both the true and false parts of the '?:' oper-
    ator must return the same type.
