Hacked around, I would say, not solved.

I guess to solve it, genhooks should produce output in binary mode,
so the content really is identical, or diff should be used to compare
output

I'm not sure I understand.  There are three possibilities:
tm.texi is out of date wrt. tm.texi.in, or the user edited the wrong
file inadvertently, or things are in sync.

That looks like another bug to me.

I opened <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45888>.
Might look into it, but not right now.
