[llvm-dev] Why does clang -E - of a header file may have different exit status?

There are no error messages.

$ clang -E - <<< '#include <bfd.h>' > /dev/null
$ echo "$?"
0

Could you try to install binutils-dev on a debian lineage linux? bfd.h
is from that package. The thing that does not make sense is that gcc
is consistent but clang is not.
