Thomas Jarosch 374af15bd4 Fix parsing linkage specifier from global function declaration
Our very own "tools/dmake.cpp" had a function declaration
featuring "static void foobar()" while the function implementation
did not have the 'static' keyword (which is perfectly legal code).

Thomas Jarosch dca65ce3da Fix FP if sizeof is used without parentheses on struct members
Right now we only support checking basic pointer types.

Token::Match( "sizeof ( %varid% )" ) won't match it.
Token::Match( "sizeof %varid%" ) did match it -> FP.
