That's weird, since the Clang manual sports examples with plain 'asm'; see:

https://clang.llvm.org/compatibility.html#inline-asm

Is there something unusual about your setup that would cause it to reject 
examples taken out of the Clang documentation? Has Clang's behavior changed 
recently, for example?

How about if you change the previous line in lib/explicit_bzero.c from this:

# ifdef __GNUC__

to this:

# if defined __GNUC__ && !defined __clang__

? Does that fix your problem?
