I don't think Clang ever could find proper includes here. See the bugs like:<br>

It works fine, it just doesn't know where to find the correct stdlib headers, so you have to use an -I argument to tell it where your stdlib headers are (arch-specific on Debians/Ubuntus/etc).<br>
<br>

What operating system are you using?<br>
<br>
What's the output of "clang -v -c test.c"?<br>

From where did you install clang?<br>
