It seems strange at least.
I don't have chapter and verse against it though.

If we change gdb to cope with this, I think the effect will be to undo what
the patches here were attempting to accomplish.
That would be fine by me -- but in that case, why not just revert
gcc to the status quo ante, preserving compatibility with existing
versions of gdb?
