First of all, it's fine to initialize a character pointer to point to a
string constant.  Just don't try to alter the constant.  If you
want to initialize a character pointer to point to a non-constant string,
try the following:

	# define CONST	"0123456789"

	char	nonconst[sizeof(CONST)];
	char	*p = nonconst;

	strcpy(nonconst, CONST);

There, that's not so hard, is it?  I don't think it's a good programming
practice to modify the value of a constant, anyway.
