26 /* caution: this mirrors macros in sys/malloc.h, and uses interfaces
27 * which are subject to change.
28 * The problems are that:
29 * - the official MALLOC macro wants the lhs of the assignment as an argument,
30 * and it takes care of the assignment itself (yuck.)
31 * - PPP insists on using "FREE" which conflicts with a macro of the same name.
