<pre>$ cat z.c
int printf;
$ clang -c z.c
z.c:1:5: error: redefinition of 'printf' as different kind of symbol
int printf;
^
z.c:1:5: note: previous definition is here
1 error generated.
The message about previous definition is definitely misleading.
That apart I'm not sure that to treat this as a fatal error is the right thing
to do.
FWIW:
$ gcc -c z.c
z.c:1:5: warning: built-in function ‘printf’ declared as non-function [enabled
by default]
int printf;
