I am not in good position to send build logs or try the alternative CFLAGS
until another long build finishes.

But the idea of the gcc version sounds promising. I am building with a gcc
from near the head. The default version of C has changed to C11 and I
know that has caused a few odd issues with RTEMS. Maybe this has
impacted the the compilation of this method.

$ gcc --version
gcc (GCC) 5.0.0 20150211 (experimental)


I will try the suggestions as soon as I can.
