Ok that information is missing in the changelog then.
Also I hope the uglification<->usefullness factor is really worth it.
The patch is certainly no slouch on the uglification side.
It also has maintenance costs, e.g. I doubt ctags and cscope
will be able to deal with these kinds of macros, so it has a
high cost for everyone using these tools. For those
it would be actually better if you used separate annotation
that does not confuse standard C parsers.
