pure and impure space as loaded can vary, and even their
relative order cannot be relied on.

numerically. */

to change the boundary between the text section and data section
when Emacs is dumped. If you define this, the preloaded Lisp
code will not be sharable; but that's better than failing completely. */

working alloca function and it should be used.
Define neither one if an assembler-language alloca
in the file alloca.s should be used. */
