build: add some warning cflags
These were in the old configure script too. Two flags are explicitly tested, because I have no idea how widespread support for them is, and testing them is just easier than trying to look them up in various gcc/clang manuals. There are people using gcc 4.2 out there, so some caution is warranted.
