Example:
#include <stdio.h>
int main() {
long int li = 0;
printf("%ln",li); // %l is the size specifier; the type specifer is missing
printf("%ldn",li); // OK
return 0;
}

which version of the Intel C++ compiler are you using and which VC? I do not get this warning with 10.1 or 11.x.

8.1 version is very old. please upgrade to 11.0. This issue is fixed in the 10.1 and newer release. Or you can try the Parallel Composer.
