---------------------------------------------------------------
Removing the const qualifier from the declaration of the formal function
argument allows the compiler to deduce the cv-qualifiers from the actual
argument to the call:
{noformat}
$ cat t.cpp && aCC -AA -V t.cpp
template <class T> void foo (T&) { }
template <class T> void bar (T*) { }
int main () {
int i = 0;
const int ci = 0;
volatile int vi = 0;
const volatile int cvi = 0;
foo (i);
foo (ci);
foo (vi);
foo (cvi);
bar (&i);
bar (&ci);
bar (&vi);
bar (&cvi);
}
