	I had a problem compiling the 'ro' text formatter submitted in
	comp.source.unix with the sun C compiler :

	Problem:
		In ro_macr.c, line 170, a call to strlen is made
		with an argument that can be NULL, giving a bus error
		on a SUN 3...

	Proposed correction:
		Replacement of all strlen calls by mystrlen, with the
		following definition:

			int mystrlen(s)
			char *s;
			{
			  if (s==NULL) return (0);
			  else return(strlen(s));
			}


	Any comment ?				Robert Lacoste.
