[U-Boot] what is the rationale for 900+ lines duplicated in common/dlmalloc.c and include/malloc.h?

just noticed, in common/dlmalloc.c, the sizable chunk:

#if 0 /* Moved to malloc.h */ /* ---------- To make a malloc.h, start cutting here ------------ */

... several hundred lines ...

#ifdef __cplusplus }; /* end of extern "C" */ #endif

/* ---------- To make a malloc.h, end cutting here ------------ */ #endif /* 0 */ /* Moved to malloc.h */

given that those lines appear to be duplicated in malloc.h, what is the purpose of them still being in dlmalloc.c? i'm just curious.
