--- Comment #3 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
Per my testing, r249070 is causing the regressions listed below. Looking at a
few cases, we're running into:

Tom's patch (plus '#include "common/common-target.h"') does cure this.

Same for "-DACC_DEVICE_TYPE_host=1 -DACC_MEM_SHARED=1", and for
"libgomp.oacc-c++", and the combination of both.
