Left over from recent reverts? (Itaru Kitayama via Openmp-dev)

Trunk Clang as of this writing leaves an error, but this looks like
it should have been fixed by reverts, no?

error: declaration conflicts with target of using declaration already in
abs(double __x)

Sadly unrelated to recent reverts. This has been broken since May 17, 2019. Differential D62046.



OK, then makes sense why I see this with official 9.0.0 release as well.
