-/* Different portions of Emacs need to call different versions of
- malloc. The Emacs executable needs alloca to call xmalloc, because
- ordinary malloc isn't protected from input signals. On the other
- hand, the utilities in lib-src need alloca to call malloc; some of
- them are very simple, and don't have an xmalloc routine.

- Non-Emacs programs expect this to call xmalloc.
