Not as much as I am.
The change should have been a non-issue.

So would I.
I'll have to get a translator or something.

That's fine by me.

Nor have I ever assumed SuSE had any intent.
As far as I'm concerned, it was just a simple oversight by Jiri.
In fact, I considered it such a minor oversight that i didn't even submit
it as a separate patch, just as i didn't separate out the update of the
copyright years.

So do I.
The extreme reaction of removing code from the
repository, simply reminds me why i spend time working on GCC rather than
GDB, and why i coded a replacement in C++ in the first place.
