MALLOC_ALIGNMENT (default: NOT defined)
Define this to 16 if you need 16 byte alignment instead of 8 byte alignment
which is the normal default.
SIZE_T_SMALLER_THAN_LONG (default: NOT defined)
Define this when the platform you are compiling has sizeof(long) > sizeof(size_t).
The option causes some extra code to be generated to handle operations
that use size_t operands and have long results.
REALLOC_ZERO_BYTES_FREES (default: NOT defined)
Define this if you think that realloc(p, 0) should be equivalent
to free(p). Otherwise, since malloc returns a unique pointer for
