All you need to do is replace fjbg.jar with your updated one, and then
run ./push-binary-libs.sh (with arguments of username and password
which allow you to push to artifactory - jsuereth can give you those
if you don't have them.) After that you will notice the
fjbg.sha1.desired file has been updated, at which point you can check
that in, and once it is merged into trunk future people will pull the
new fjbg.jar.

Those future people will have to run pull-binary-libs.sh manually to
get the update (or maybe it works automatically if you use sbt, but
I'm still on ant, where it will notice a change to scala-compiler.jar
and pull new libs, but not to anything else because it is comically
challenging to write a conditional like if "a or b or c" in antese.)

Thanks. A pull request will follow shortly.
Regarding the fact that people might not have updated fjbg.jar file. It's not a terrible situation because it's going to only affect those that use -Yvirtpatmat and happen to have pattern exactly like this:
(x: Int) match {  case _ => ... }
(with no other cases defined)
You can see we I don't need to worry about it too much.
