Is anybody actually still using GCC 4.7 on master (towards LO 6.0, by now)?

Just tried to build recent master against some GCC 4.7.4 (on F25, using 
system's libstdc++ 6.3 at runtime), and that doesn't work well, causing 
spurious -Wsign-compare warnings, spurious errors about allegedly 
implicitly noexcept(false) dtors of std::exception derivations, and 
failure to compile usage of thread_local in 
comphelper/source/misc/threadpool.cxx (where support for thread-local 
storage was only "partial" in GCC < 4.8, according to 
<http://en.cppreference.com/w/cpp/compiler_support>).  So I wonder if 
anybody still manages to build with anything less than GCC 4.8?

(LHM's tb56 appears to be using GCC 4.8 by now, and that used to be one 
with a notoriously old compiler.)

If there's no objections, I'd bump current master towards LO 6.0 to GCC 4.8.
