note that the current code is not compatible with glibc
http://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/gnu/bits/utmpx.h
vs
http://git.musl-libc.org/cgit/musl/tree/include/utmpx.h
it seems the __ prefix depends on _GNU_SOURCE
and the 64bit abi is different on musl
(see ut_session and ut_tv)
