<div>
<pre>Compile the following code, clang compiles it without error: it
should generate a diagnostic.
enum e1 {a, b};
enum e2 {c, d};
void f(enum e1);
void f(x)
enum e2 x;
{
return;
}
Instead, gcc rejects the above code:
gcc code0.c
code0.c: In function 'f':
code0.c:7:10: error: argument 'x' doesn't match prototype
enum e2 x;
^
code0.c:4:6: error: prototype declaration
void f(enum e1);
^</pre>
