Re: Emacs 28 on OSX: emacsclient.c:1415: warning: implicit declaration of function 'openat'

[Keith David Bershatsky]

Thank you.  The latest patch fixed the `openat` build issue on OSX 10.6.8 (with 
Xcode 3.2.6) using:  ./configure --with-gnutls=ifavailable

The next issue with the build is at nsterm.m.  Would you like me to open a 
separate email with a new subject title?
