That's a violation of the C standard and so should be fixed.

The real culprit here is that Emacs config.h includes <stdlib.h>. It's 
generally not a good idea for config.h to include headers like 
<stdlib.h>, as that's brittle (as shown here).

I adjusted Gnulib to work around this particular problem and merged that 
into Emacs. However, the culprit may cause other lurking issues so I 
also installed the attached patches to Emacs so that config.h no longer 
includes <stdlib.h>.

In <https://bugs.gnu.org/52455#21> I just now proposed removing 
no-longer-working code that attempts to support unexec on macOS. That 
would have simplified the attached patches.

It would also simplify things to remove the HYBRID_MALLOC code but I 
don't know whether that stuff is still used.
