Subject: [PATCH] Remove definition of _DARWIN_USE_64_BIT_INODE
MIME-Version: 1.0

It’s not needed in currently-supported macOS versions, and was
problematic anyway in MacOS X 10.5 which was the only version that
could use it.  Problem reported by Peter Eisentraut in:
https://lists.gnu.org/r/bug-autoconf/2020-02/msg00004.html
* lib/autoconf/specific.m4 (AC_SYS_LARGEFILE):
Don’t define _DARWIN_USE_64_BIT_INODE.
(cherry picked from commit 2864a5dbbfeb5383451ff1858cc16cdae05d738c)
