I'm running the following

test.cpp

#include <iostream>
#include <limits>
#include <cstdlib>
using namespace std;

int main(int argc, char** argv) {
    long value = numeric_limits<long>::min();
    value = abs(value);
    cout << value << endl;
}

Depending on what computer I compile and run the program on, I'm getting different results.

Either I get:

abs(numeric_limits<long>::min())

Or I get:

numeric_limits<long>::min()

In the latter case, abs() doesn't seem to be performed. I'm wondering what accounts for this difference and how I should accommodate it. Should I compute abs() in a different way?
