I cant reproduce this - after trying several combinations of types.

What are the types of the variables?  This example compiles fine.
-----

#include	<u.h>
#include	<libc.h>

long	result;
long	col, plane1, plane2;
uchar	tuplerow1[100][100], tuplerow2[100][100];

void
foo(void)
{
	result = (int)tuplerow1[col][plane1] > (int)tuplerow2[col][plane2] ?
(int)tuplerow1[col][plane1] - (int)tuplerow2[col][plane2] :
(int)tuplerow2[col][plane2] - (int)tuplerow1[col][plane1];
}
