$ cat test.cpp
namespace x {
extern char *foo;
};
using namespace x;
char *foo;
char bar()
{
return *foo;
}
$ g++ test.cpp -fsyntax-only
test.cpp: In function Âchar bar()Â:
test.cpp:8: error: reference to Âfoo is ambiguous
test.cpp:5: error: candidates are: char* foo
test.cpp:2: error: char* x::foo
test.cpp:8: error: reference to Âfoo is ambiguous
test.cpp:5: error: candidates are: char* foo
test.cpp:2: error: char* x::foo
The same error is shown twice.
I think it would be enough to show the error once.
This is with:
$ g++ -v
Using built-in specs.

Same happens with g++-4.2, and trunk (r141407), g++-4.1 appears to infloop.
