Gcc4.2 in linux and gcc3.4.5 in windows cannot distinguish between positive and negative numbers.

Gcc4.2 in linux and gcc3.4.5 in windows cannot distinguish between positive and negative numbers-general Linux technology-Linux programming and kernel information. For more information, see the following. "Linux programs cannot distinguish between positive and negative numbers. For example,-10 and 10 are considered equal.

Int main (){
Int I = 2;
If (-10 * abs (I-1) = 10 * abs (I-1 ))
Printf ("OMG,-10 = 10 in linux! \ N ");
Else
Printf ("nothing special here \ n ");
}

For the same C code, the result of compiling and running in windows and unix systems is nothing special here. Only linux gets-10 = 10.

Well, our gcc made a low-level error here. "
