$ clang --std=c11 test.c
test.c:3:5: warning: implicit declaration of function 'static_assert' is
invalid in C99 [-Wimplicit-function-declaration]
    static_assert(1, "This shouldn't happen");
1 warning generated.
Undefined symbols for architecture x86_64:
  "_static_assert", referenced from:
      _main in test-FjUiYF.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see

clang++ supports static_assert because of it's definition in C++ library

But in the same time Apple doesn't ship static_assert definition for C
$ grep static_assert /usr/include/assert.h
$ echo $?
