# Debugging flags possible:  DEBUG_MEM DEBUG_MEM_CORRUPT DEBUG_MEM_DUP_FREE
# DEBUG_MEM is most basic, just checks magic numbers when freeing
# DEBUG_MEM_CORRUPT checks every free block to see if magic numbers ok, every
#                   call to alloc_mem
#		    Also makes calls to void check_free_mem(void) check for
#		    corrupted free memory blocks.
# DEBUG_MEM_DUP_FREE checks to see if freed blocks are overlapping every call
# 		     to mem_alloc.
