[Bug c++/17609] New: spurious error message after using keyword

[papadopo at shfj dot cea dot fr]

The 3.4 C++ compiler emits two errors on the following code. Only the first one
should be emitted (that's the case with gcc 3.3). That's not a serious bug since
the second error message disappears when the first one is fixed, but it's
disturbing nevertheless.

$ cat > foo.cc
#include <iostream>
void function1() {
    cout;
}
using namespace std;
void function2() {
    cout;
}
$ 
$ g++ -c foo.cc
foo.cc: In function `void function1()':
foo.cc:3: error: `cout' undeclared (first use this function)
foo.cc:3: error: (Each undeclared identifier is reported only once for each
function it appears in.)
foo.cc: In function `void function2()':
foo.cc:7: error: `cout' undeclared (first use this function)

[Bug c++/17609] [3.4 Regression] spurious error message after using keyword

[reichelt at gcc dot gnu dot org]

------- Additional Comments From reichelt at gcc dot gnu dot org  2005-09-21 15:12 -------
This is now fixed in GCC 3.4.5.

The new testcase g++.dg/lookup/error1.C will be added to mainline
and the 4.0 branch. In the meantime I'll keep the PR open.
