>Description:
When compiling libgcj with -Wshadow I get this warning
repeatedly:

../../../libgcj/libjava/interpret.cc:670: warning: declaration of `index' 
   shadows global declaration

I don't know where `index' is declared globally.
I'm guessing it is a C string function that somehow
gets declared.

First, I don't really want this warning.  I don't care
if I shadow a function name.

Second, and more importantly, it would be nice if
-Wshadow printed the location of the conflicting
declaration.  Otherwise I have to use "gcc -E" and dig
backwards from there to find it, which is a pain.
