// Given the following C++ code

void f( char * str)
{

	char * & m = const_cast<char *>( str);
}

/*
then g++ 332 says not a lot.

[dcb@localhost src]$ ~/gnu/gcc332/results/bin/g++ -c -g -O2 -Wall -ansi
-pedantic cc.cc
cc.cc: In function `void f(char*)':
cc.cc:7: warning: unused variable `char*&m'
[dcb@localhost src]$

But Intel C++ 8.0 says

[dcb@localhost src]$ icc cc.cc
cc.cc(7): error: initial value of reference to non-const must be an lvalue
        char * & m = const_cast<char *>( str);
                     ^

compilation aborted for cc.cc (code 2)
[dcb@localhost src]$

One compiler must be wrong.
