84   Minimum overhead per allocated chunk: 4 or 8 bytes
85        Each malloced chunk has a hidden overhead of 4 bytes holding size
88   Minimum allocated size: 4-byte ptrs:  16 bytes    (including 4 overhead)
89 			  8-byte ptrs:  24/32 bytes (including, 4/8 overhead)
111   Maximum overhead wastage per allocated chunk: normally 15 bytes
297   overhead by defining INTERNAL_SIZE_T to be a 32 bit `unsigned int'
702       to avoid measurable overhead, so the default is 0.  However, in
