It does though, in the code example I have posted elsewhere. You can just 
put a sequence of unconditional free(3) calls, which is much shorter than 
useless things like

    if (ptr)
        free(ptr);

which I see all too often.

By the way, the C++ “delete” statement is similarly specified to treat an 
attempt to dispose of a NULL pointer as a harmless no-op.
