I delved into `lib/fcntl.h` and found `O_BINARY` is defined in it.
Then I found that `binary-io.h` includes `fcntl.h` with `#include <fcntl.h>`,
which means it mightuse my system's version of `fcntl.h`. I found that system's
`fcntl.h` has no `O_BINARY` defined and I happened to have `export 
in my .zshrc so the compiler used system's instead of emacs'(which is supposed 
to be used).
I deleted the `C_INCLUDE_PATH` definition in `.zshrc` then successfully 
compiled it.

Thanks for the help!

 O_BINARY is supposed to be defined in lib/fcntl.h, please look there
 for why this doesn't work for you.

 In any case, I suggest to report this using report-emacs-bug.
