I am seeing a compilation error in alloc.c o= n line 3287 on Mac OS X due to SPARE_MEMORY being undeclared.

Starti= ng on line 193 of alloc.c is the following code block that attempts to defi= ne SPARE_MEMORY.

#ifndef SYSTEM_MALLOC
/* Amount of spare memory to keep in large res= erve block.=A0 */

#define SPARE_MEMORY (1 << 14)

How is SPARE_MEMORY defined on systems that do = define it?=A0 Is the above change the correct one?=A0 It fixes the problem = on Mac OS X but I do not want to make a change that will cause problems for= other operating systems.
