 Thanks for the pointer, but, no, not necessarily. The problem in #10761
 happened due to calling from NSS to NSPR. After libraries are folded there
 is no cross-dll call here anymore. There might be similar problematic
 calls although this is unlikely at least according to Jacek.

 Anyway, we keep the backout for now as the alternative is pulling in a
 bunch of build changes whose stability risks for ESR45 are unknown.

 We bump the mingw-w64 commit we use to
 a0cd5afeb60be3be0860e9a203314c10485bb9b8 as this one is at least needed
 for Tor Browser based on Firefox > 45 anyway.

 arlolra: FWIW: I did not figure out why you don't need the Werror patch
 for Tor Messenger. Even if I use a more or less default .mozconfig and
 default build flags I hit that one when building Tor Browser.
