--- Comment #2 from Jack Howarth <howarth.at.gcc at gmail dot com> ---
Current gcc-4_9-branch at r221965 suffers the same bootstrap comparison failure
on x86_64-apple-darwin14 with Xcode 6.3's Apple Clang 6.1 compilers and on
x86_64-apple-darwin13 with Xcode 6.2 and the llvm.org 3.6.0's clang compilers.
