--- Comment #3 from andre.mccurdy at linaro dot org ---
Thanks. I have updated the original summary since it was unclear:
The bug is not that the __has_include feature can't be used in 4.9.x.
The bug is that __has_include is defined in gcc-4_9-branch, which causes
"#ifdef __has_include" be ineffective as a guard to prevent attempts to use the
__has_include feature.
