further missing c11 things:

time.h needs TIME_UTC for timespec_get base parameter
stdalign.h should only define alignas and alignof ifndef c++
assert.h needs static_assert ifndef c++
float.h needs *_DECIMAL_DIG and *_HAS_SUBNORM (i have a patch for this)
uchar.h
stdatomic.h (or __STDC_NO_ATOMICS__)

(thread_local, alignas, alignof, static_assert, noreturn are keywords
in c++, stdnoreturn.h is not specified by c++14 so that probably does
not need the ifndef but the others do)
