the modulus operator in Windriver C++

Would someone with ready access to Windriver C++ please run the following short program and post whether it returns "-179" or "+181" ?

Code:

void main (void) {

signed int err;

err=(-179)%360;

printf("err=%d",err);

}

The old C compiler I have here returns -179, but I am told that newer compilers return +181.

Thanks.

Page 82 of ISO/IEC 9899:TC3 (attached) shows that

(-179)%360 must be -179
