Unomitted frame pointers

People sometimes mismatch the string names, e.g.:

          write (2, HELLOSTRING, strlen(JELLOSTRING));
                                        ^

To reduce that hazard we have a macro:

#define TEXTARG(s)    s, (int)strlen(s)

          write (2, TEXTARG (HELLOSTRING));

But it looks odd, and people don't use it as much as they could.

P.S.  here is another thing gcc misses:

          memcpy("hi", p, 2);  /* "cannot modify string literal" */
