The local context engine does not find variables in any "function call" 
like syntax, only after { block starts.  It is not impossible to add 
support, it is just that similar blocks, such as for(int i ... never had 
structured data that mattered enough to warrant the effort.

There is a project active for a g++ plugin that David Engster is working 
on that will improve the c++ support in CEDET/Semantic.  Hopefully that 
will help with cases like this since it will have the full preprocessor 
doing the work.
