No, I disagree.

Yes, that's true, but it "lies" about the parameter and gives the compiler no
chance to warn me if I call gfree(p) instead of gfree(&p)! (And naming it
gfreep() won't help much as long as nobody can use the "p" in the function
name for checks. I, of course, could/should but tend to forget and make
mistakes and that's were the compiler assists with its warnings.)

Thinking about avoiding the cast, maybe a macro like

  #define nfree(p) { free(p); p = NULL; }

would be a suitable replacement for gfree()?
