[PATCH] D34158: For Linux/gnu compatibility, preinclude <stdc-predef.h> if the file is available

This version is fine with me. The only contentious part is whether it should be opt-in or opt-out for platforms, so getting this version in and revisiting the issue again later is OK from my perspective.
