The attached patch fixes symlinks to point to gnuconfig files within Gentoo Prefix and not to (potentially non-existing) system files.

Quite a good catch. Thank you very much! I applied it, and revbumped 2.2.4, such that people should get your fix. Thanks again, what an oversight!
FYI: It appears that this patch fixed bug 220917 AND bug 220831 which I thought were libtool-2 issues but they haven't been touched since your patch went in. So..thanks again!
Comment #3 is invalid, sorry I jumped the gun and sorry for the bug spam =/
