Well, in that case, ignore the patch :)

I implemented it because I could not figure out how to avoid
exporting all symbols from an executable with binutils
2.9.5.0.37 (debian stable).  I can maintain that version
internally in Opera until we all got working symbol versioning
(with executables) on all platforms.

Incidentally, I'm not sure that it is obvious that symbol versioning
actually can be used to "unexport" symbols.  I overlooked it completely
when looking for a way to do it.  And I was trying to find that
functionality in the info pages for ld and gcc.  Now that I know what
to look for, I can find it.
