Thanks, done.

So I tried compiling Emacs 26 on macOS 10.13. I configured with
`./configure' and everything went fine. However, when I ran `make', the
following error appeared:



/Applications/Xcode.app/Contents/Developer/usr/bin/make -C lib all
  CC       acl_entries.o
  CC       explicit_bzero.o
  CC       fpending.o

      mode = va_arg (arg, PROMOTED_MODE_T);
                          ^
1 error generated.
make[1]: *** [open.o] Error 1
make: *** [lib] Error 2



Upon inspecting this error, I see the following comment above the
offending code:

/* We have to use PROMOTED_MODE_T instead of mode_t, otherwise GCC 4
   creates crashing code when 'mode_t' is smaller than 'int'.  */

I also see the following output regarding `open.c' when I compile with
`make CFLAGS="-v"':

Anyone know how to fix this error? I'd hate to run into something like
this in a non-release-candidate release...
