I am using Texinfo 4.13.

Making info here is already so slow that neither of these is an option
for me.  In the good old days it was a pure pleasure to work with
makeinfo - maybe due to the fact that the Elisp manual was split in
those days or, because on Windows a much simpler build script was used.
After a text change, I could produce the corresponding updated and
reverted *info* buffer practically on-the-fly.  Nowadays it takes me
half a minute to do so.  For me it's the worst pain that happened in the
recent development of Emacs.

It would have been good to read something about this in NEWS or
somewhere else.  I already "fixed" at least one such link in the release
version ...

I can't reproduce it with emacs -Q so it might as well be related to my
setup.

Thanks for the information, martin
