Yeah, starting with r197315 we warned about it, r198730 fixed that (no warning
nor error), and r198842 started reporting error instead on this.

Is there a patch to get this working with gcc 4.8.1? How far back into the
history will the patch need to reach.

Just search gcc-patches around the date of Comment #3, no?

I will have to patch it up to that point from gcc 4.8.1 to Comment #3, is the
main repo git or subversion?

What I should have asked is what revision is gcc 4.8.1 and what revision was
the fix put into trunk?

svn log svn://gcc.gnu.org/svn/gcc/branches/gcc-4_8-branch
svn log svn://gcc.gnu.org/svn/gcc/tags/gcc_4_8_1_release

show that the fix went into the branch at r200836, and the release was at
r199525.  You can extract the patch from SVN with

svn diff -c200836 svn://gcc.gnu.org/svn/gcc/branches/gcc-4_8-branch

It doesn't depend on anything else since the 4.8.1 release.
