Do you see something obviously wrong with the attached patch?
I haven't tested it yet, and I am not sure how much I can test it,
given that old-style renamings have been replaced 6 years ago.
I was looking at the option of removing support for them, but
I actually know of some users still using an ancient version
of the compiler but with a new version of the debugger...
