Basically these two functions should produce the same code, the check for NotFound is not needed 
at all.
void g(); void h(); void o();
void t(int l, int *y)
{
int i;
int NotFound;
o();
for(i = 0, NotFound = 1;NotFound && i<l;i++)
{  if (y[i])  { NotFound = 0;  g();  } }
h();
}


void t1(int l, int *y)
{
int i;
int NotFound;
o();
for(i = 0, NotFound = 1;NotFound && i<l;i++)
{  if (y[i])  { NotFound = 0;  g();  break; } }
h();
}
