Public bug reported:
This command fails saying that limits.h cannot be found:
echo '#include <limits.h>' | clang -v -xc -o /dev/null -
This is the full verbose output from it:

End of search list.
In file included from <stdin>:1:
/usr/include/limits.h:124:16: fatal error: 'limits.h' file not found
# include_next <limits.h>
^
Now, my first thought was that my limits.h file had been deleted
somehow, but running "locate limits.h" shows that there is a limits.h in
/usr/include, which clang searches through according to the verbose
output.
This has only been a problem since upgrading to Ubuntu 13.10.
