It is not a matter of version, but parameters. You put a lots of -W (I
wonder if it would not be shorter to use -pedantic, -Wextra and then
disable some) but miss -O1 (or higher) so -Wuninitialized does

Currently there are a small group of warnings left, specially in .cpp
files about signed with unsigned comparison or offsetof. Other small
handful are about printf, caused mostly by LLP64 vs LP64 and a
meaningless intprt_t (the warnings probably only appear on ILP32) for
which I have a tentative fix, but being "lib" files no idea if worth.
