cc(1) errors in libc includes

Hi -current,

today I built -CURRENT for the first time in a VM and installed from nfs
mounts. But now cc(1) from base seems to be broken, as it fails
compiling a simple hello-world program with errors in include files from
the libc. The previously installed clang40 works just fine for this
task, but since I lost track of -CURRENT around the time of the ino64
changes, I don't necessarily trust it to do the right thing.

Do you have any solutions for me how to get the compiler working again?

Below the uname info and the actual error messages:
