my reading of it is that to prevent too many FTBFSes while introducing
4.6 in Debian, some changes were delayed (“reverted through Debian
patches”) until 4.6.1 is released and uploaded.

Assuming you're talking about -Wunused-*, those are mentioned on the
upstream upgrading / porting page:

| New -Wunused-but-set-variable and -Wunused-but-set-parameter warnings
| were added for C, C++, Objective-C and Objective-C++. These warnings
| diagnose variables respective parameters which are only set in the
| code and never otherwise used. Usually such variables are useless and
| often even the value assigned to them is computed needlessly,
| sometimes expensively. The -Wunused-but-set-variable warning is
| enabled by default by -Wall flag and -Wunused-but-set-parameter by
| -Wall -Wextra flags.

I don't think more changes are planned for the 4.6.x series; you'll
have to wait for 4.7 to get more changes.
