    cc-defs.el: Update "virtual semicolon" comments.
    
    cc-engine.el (c-crosses-statement-barrier-p): Recoded to scan one line at
    at time rather than having \n and \r explicitly in c-stmt-delim-chars

    (c-opt-cpp-macro-define): Make into a full language variable.

    AWK Mode (including \n, \r) removed, no longer needed.
    
    cc-mode.el (c-mode, c++-mode, objc-mode): Invoke
    c-make-macro-with-semi-re.

    variables.
    (c-make-macro-with-semi-re): New function
