bug#28793: 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 acl_entries.o
CC explicit_bzero.o
CC fpending.o
CC fstatat.o
CC getopt.o
CC getopt1.o
CC lstat.o
CC memrchr.o
CC mktime.o
CC open.o
open.c:75:27: error: unknown type name 'PROMOTED_MODE_T'
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...
