Does it?
--------------------
#include <stdio.h>
int main(void)
{
int i = 0;
while (i++ < 25)
;
printf("%d\n", i);
return 0;
}
--------------------
davem@sunset:~/src/GIT/linux-2.6$ gcc -O2 -o x x.c
davem@sunset:~/src/GIT/linux-2.6$ ./x
26
davem@sunset:~/src/GIT/linux-2.6$
I'm getting extremely tired of these "off by one" patches, to be
honest with you.
