hi folks.
i'll be switching the i386, sparc and sparc64 ports to GCC 6.4.0 this weekend. the alpha, mips, and powerpc ports are also mostly ready to go, and arm could with some more testing. unlisted ports need testing, but should build. (most ports haven't had their full release build tested, which is the main reason most of these are not ready to switch right now.) this will cause build failures that need tools/gcc objdir and the destdir to be cleaned up, if not more. please clean those dirs and try again, and if more failure, try a completely clean build. for now, you can force GCC 5 builds with "HAVE_GCC=5". as always, please send-pr any issues you find. thanks! .mrg.
