should we change dead links in source tree to archive.org?

[Andreas Weber]

Dear all,

there are approx. 500 links in the source tree (gnulib excluded) and
many of them are dead now, for example

inpolygon.m: http://local.wasp.uwa.edu.au/~pbourke/geometry/insidepoly/

but archive.org has a copy. The newest I've found is
https://web.archive.org/web/20070923104638/http://local.wasp.uwa.edu.au/~pbourke/geometry/insidepoly/

So my question is: Should we replace dead links with archive.org links?
