Hi Carl,
No, it should not be backported to GCC 7. To clarify what I was saying:
these header files exist in branches/ibm/gcc-7-branch but do NOT exist
in branches/gcc-7-branch. That IBM-private branch (used for AT 11.0)
should have these macros added, but the main gcc-7-branch should not.
We don't want any new files added anywhere as part of this work.
Thanks,
Bill
