My understanding from reading the bug and seeing the diff, is that you
should just apply the patch.

Recompiling code that uses the bar() macro would be indeed nice, so
maybe you could unpack all the packages that build-depend on your
library, and grep them for bar()? If you send a list of matches to
debian-release@lists.debian.org, we can rebuild them with binNMUs then.

Cheers,
