Subject: [boost] Libc++ failures on linux

So I tried to add my first linux regression runner using libc++ with clang,
and I'm seeing the following error saying it can't find <cstddef>:
"clang++-3.9" -c -x c++ -Wno-c99-extensions -std=c++1z -stdlib=libc++ -O0
-g -fno-inline -Wall -g -m64 -DBOOST_ALL_NO_LIB=1
-DBOOST_TEST_NO_AUTO_LINK=1 -DBOOST_TIMER_STATIC_LINK=1 -I".." -o

In file included from ../boost/config.hpp:44:
../boost/config/select_stdlib_config.hpp:18:12: fatal error: 'cstddef' file
# include <cstddef>
1 error generated.
However when I try to compile the following program on the same docker
int main(int argc, char* argv)
size_t three = 3;
$ clang++-3.9 -stdlib=libc++ -std=c++1z basic.cpp
It works fine
$ echo $?
I can build this sample file fine with the whole command line shown above,
so it doesn't seem to be one of the other options conflicting.
Any thoughts on why boost code wouldn't be able to find this but some basic
One relevant detail, I'm building with clang 3.9, however the libc++
version that I'm using (ubuntu default) is the one that shipped with clang
3.7. That shouldn't preclude including a file!
I also found a couple old threads with the same error, but never any good
