fix all implicit conversion between signed/unsigned pointers sadly the C language does not specify any such implicit conversion, so this is not a matter of just fixing warnings (as gcc treats it) but actual errors. i would like to revisit a number of these changes and possibly revise the types used to reduce the number of casts required. 2011-03-25 16:34:03 -04:00			`const unsigned char l=(void )_l, r=(void )_r;`
