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

jyknight added a comment.

I'd still _very_ much like a solution that is acceptable for all libc to use, and have that on by default.

However, I guess this is fine.

Only concern I have is that it seems odd that so many test-cases needed to be changed. What fails without those test changes?
