        <pre>I'm working with a project that wishes to use -std=c89 -pedantic for
testing.[1]

Compiling a POWER8 source file that uses vector built-ins [2], such as vec_ld,
results in the following. It looks like Clang disagrees with 'inline' from
<altivec.h>.

I don't have a reproducer at the moment. The only POWER8 machine I have access
to with Clang 8.0 is at Travis. The GCC compile farm has old versions of Clang,
and I am getting different compile errors.
