[Bug c++/8045] Missing "unused variable" warning

["flameeyes at gentoo dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I think this applies to 4.3 as well, as the following code does only warn in
the second function:

#include <stdlib.h>
#include <string.h>

char* oldstyle(const char *foo) {
  size_t foolen;

  if ( foo == NULL )
    return NULL;

  foolen = strlen(foo);

  return strdup(foo);
}

char* newstyle(const char *foo) {
  if ( foo == NULL )
    return NULL;

  const size_t foolen = strlen(foo);

  return strdup(foo);
}

And I could really make use of such a warning in xine-lib's code :)
