[PATCH] Attribute parsing following labels

[Richard Smith]

It should be possible to handle this case without tentative parsing or
lookahead. Consume the attributes onto a new list; if the next token is a
semicolon, then push them into the label's attribute list; otherwise,
ParseStatementOrDeclarationAfterAttributes.

What does GCC do if there are #pragmas between the case label and the
attribute, and/or between the attribute and the semicolon?
