7a8dfe707b compiler: Check for EOF in malformed signatures. 
When parsing a malformed function declaration with invalid parameters,
    gccgo would infinitely loop looking for the end of the function
    declaration.

5d44e40bb5 compiler: Handle newlines in general comments. 
On comments, the specification says
    (http://golang.org/ref/spec#Comments): General comments start with the
    character sequence /* and continue through the character sequence */.
    A general comment containing one or more newlines acts like a newline,
    otherwise it acts like a space.
