are boost::mutexes from different boost versions ABI compatible, provided that the modules (boost thread library, my own) are compiled with the same compiler?
In general, no. In particular cases, yes: the boost::mutex implementation changes very rarely. The breaking changes I can remember were 1.34.1/1.35.0 and 1.35.0/1.36.0
My question arises because I'm creating a windows DLL with class methods taking a boost::mutex& from let's say boost 1.38, but an application (the EXE) might use e.g. boost 1.39.
Boost 1.38 and 1.39 should be compatible; the code is almost completely unchanged (I think there was a fix for some broken code, but the old version was broken).
