delete and delete[] are (in theory) guaranteed to work with NULL. Now,
I don't know if all the compilers do the right thing...
And for "free", I don't know if it should work with NULL...

just a little correction, the macros do something like "if (p) free(p);
p = NULL;"
I suggest to do (at least) "if (p) { free(p); p = NULL; }"

I would go for #1. Anyway sometimes we will be still forced to use free
(for instance, if Gtk+ gives us a pointer and states that we should free
it, we should use g_free and no delete).
