Yes I know this, but it is painful (for C++) and slow.  I suppose all 
the information on ever used (for lookup or instantiation) classes, 
methods, functions and variables is available during compilation and so 
extracting this information where it is available (in the compiler!) 
would be easy (at least for someone understanding the C++ parser). 
Running delta for two days just to get information the C++ compiler has 
in the first place doesnt sound right.

Of course delta will assist in reducing the testcase after the compiler 
has stripped all unused code.
