Subject: 26.0.90; Compile error with Emacs 26 on macOS 10.13

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       explicit_bzero.o

                          ^
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...

PROMOTED_MODE_T is defined in src/config.h, please see what happened
there.  On my system, I see this in config.h:

  /* Define to the type that is the result of default argument promotions of
     type mode_t. */
  #define PROMOTED_MODE_T int

On another system I see this:

  /* Define to the type that is the result of default argument promotions of
     type mode_t. */
  #define PROMOTED_MODE_T mode_t

Thanks for the tip. I see no results in my src/config.h when I run `M-x
occur PROMOTED_MODE_T'

Did I miss something in the configure stage? I'm sure that this can't be
right and there must be something odd on my end.

That's strange.  src /config.in includes this:

  /* Define to the type that is the result of default argument promotions of
     type mode_t. */
  #undef PROMOTED_MODE_T

Do you see it?  (Please don't rely on "M-x occur", it's possible that
it fails to find the string for some unrelated reason.  Please search
manually around line 1470.)

Does config.log include any references to "promoted mode_t"?

Ok, so it turns out that I just needed to do `make distclean' and re-run
`./autogen.sh'. I guess my `src/config.in' was out of date and so that
is what caused the issue. Everything is fine now!

Thanks a lot for the advice; feel free to close this ticket.
