Description

#define DEF1 1
#define DEF2 DEF1

#ifdef DEF1

int main(){
    return DEF1;
}
#endif

Bug: Find All References only finds the "return DEF1;" and not the cases in the #define/#ifdef. VS handles that case correctly.

It also affects rename (which uses find all references).

Research direction

Start with the supplied C preprocessor example and trace the Find All References path used by Rename Symbols. Done means references in both #define and #ifdef statements are found, and renaming covers those occurrences as well as the return statement.
