--- Comment #1 from Eric Gallager <egallager at gcc dot gnu.org> ---
Confirmed, here's an example:

$ cat 82013.c && /usr/local/bin/gcc -c 82013.c
int foo(int)

int foo(int i)
{
        return i + i;
}
82013.c: In function ‘foo’:
82013.c:4:1: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘{’
token
 {
 ^
82013.c:1:1: error: parameter name omitted
 int foo(int)
 ^~~
82013.c:6:1: error: expected ‘{’ at end of input
 }
 ^
$

For comparison clang says:

$ /sw/opt/llvm-3.1/bin/clang -c 82013.c
82013.c:1:13: error: expected ';' after top level declarator
int foo(int)
            ^
            ;
1 error generated.
