Isn't it --enable-checking=yes vs. --enable-checking=release ?
Bet that is the most important change since 4.9.0 branch creation.

AIX bootstraps at the gcc-4_9-branch creation point, but fails at GCC 4.9.0
release point. Trunk also bootstraps successfully. I am trying to bisect.

r209304 okay
r209518 fail

Okay, I can confirm this now. Bootstrap is working on trunk and was working at
the point of the branch, so this is due to some 4.9-specific patch.

I have been bootstrapping GCC trunk and 4.9 on AIX 7.1 without any failures.
