Another variant (invalid) :
$ cat z1.c
void fn1 ()
{
void fnx ()
int n;
int a[n];
}
$ gcc-7-20170205 -c z1.c
z1.c: In function 'fnx':
z1.c:6:1: error: expected declaration specifiers before '}' token
}
^
z1.c:5:7: error: declaration for parameter 'a' but no such parameter
int a[n];
^
z1.c:4:7: error: declaration for parameter 'n' but no such parameter
int n;
^
z1.c:6:1: error: expected '{' at end of input
}
^
z1.c: In function 'fn1':
z1.c:6:1: error: expected declaration or statement at end of input
