Building with compile-pentium-valgrind-max (without safemalloc) defines my_free() without flags,

so a typo on flags will go unnoticed; I put flags in this my_free() definition (as a no-op which
will still make the compiler check correctness of the flags). Applied: this caught a typo in my_realloc.c. Kindly approved by Konstantin and Mats.
