[cfe-dev] Preprocessor::LookNext

[Argiris Kirtzidis]

Hi,

The "nested-name-specifier '::' " syntax occurs at enough places that it 
would really simplify the code if an efficient 
Parser::GetLookAheadToken(1) could be used.

I attached  a Preprocessor::LookNext implementation for this 
(pp-looknext.patch).
In the "parse-labeled" patch I use LookNext to determine a label and use 
a separate Parser::ParseLabeledStatement.

Let me know what you think.
