When I ran "make" the compiler complained:

editfns.c:2063:18: warning: unsequenced modification and access to 'sa_avail' [-Wunsequenced]

This correctly diagnoses undefined behavior in that C function. I didn't investigate what happens on that platform is as it's easier to fix the problem on all platforms. I propose installing the attached obviously-safe patch into the emacs-27 branch.

There were several deprecation warnings when compiling but I assume we don't care about them in this older branch.

"make check" reported four unexpected failures. Perhaps a macOS expert could be persuaded to look into them. A tarball of the failed logs is attached.
