That sounds like a better alternative. It may be a bit more work now,
but on the long term the regex method is rather brittle as it relies on
a naming convention. As Alan pointed out, it may be a noop in many libs
as all the symbols are part of the public API.

It would be nice to hear from Christian on what prompted this patch. Any
incident occurred recently or something along those lines?
