I also ran up against the deprecation of std::mem_fun and std::mem_fun_ref in a recent migration. Easy enough to replace with lambda expressions, but one more hurdle to running C++17 code.

all compilers have ways to reinstate them to make porting easier, e.g. /D_HAS_AUTO_PTR_ETC=1 on msvc, -D_LIBCPP_ENABLE_CXX17_REMOVED_FEATURES=1 on clang...
