Which compiler? If this is Borland's compiler, then there should be
some clarifications:

#define SIZE 65500u
SB> int *segments[SEGMENTS];
int far* segments[SEGMENTS];

unsigned i, j, k;

SB> printf("malloc segment %d\n",i+1);
printf("malloc segment %u\n",i+1);
SB> segments[i]=(int *)malloc(SIZE);
segments [i] = (int far*)farmalloc(SIZE);
[...]

SB> printf("loop: %d\n",k);
printf("loop: %u\n",k);
SB> printf("segments[%d][%d]=%d\n",i,j,segments[i][j]);
printf("segments[%u][%u]=%d\n",i,j,segments[i][j]);
