I read Keith's response as: the symlink is wrong.
I read the glib FAQ as:     the symlink is wrong.
I read Linus' response as:  the symlink is wrong.

Who is contradicting who here?

(perhaps that last sentence in the glibc FAQ is confusing, however the
rest of it clearly says that glibc contains its own version of those
files, and a symlink should *not* be used. I think the part "[...] you
may have to remove any symlink [...]" is clear enough).
