building gcc 4.5.4 fails on libiberty/copying-lib.texi

[Oliver Kullmann]

That we have a gcc-build-bug seems indicated by

http://gcc.1065356.n5.nabble.com/Bug-other-51678-New-make-pdf-is-broken-in-libiberty-td399738.html

And here

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50900

is another discussion of this issue, containing at the bottom
also a link to a corrected copying-lib.texi.
