lrint() incorrect results.

["Luke Hutchinson" <lukeh-temp-email at hotmail dot com>]

lrint() does not appear to be working correctly under Cygwin.

The following simple test program compiled with g++ 3.3.3 demonstrates the 
problem.

#include <iostream>
#include <cmath>

int main(void) {
   std::cout << "lrintf(0.5f)\t"  << lrintf(0.5f)  << "\n"
                "lrintf(-0.5f)\t" << lrintf(-0.5f) << "\n"
                "lrint(0.5)\t"    << lrint(0.5)    << "\n"
                "lrint(-0.5)\t"   << lrint(0.5)    << std::endl;
   return 0;
}

The output is

lrintf(0.5f)    0
lrintf(-0.5f)   0
lrint(0.5)      2
lrint(-0.5)     2

Running the same code under Linux (fedora core 1) gives the expected results 
of,

lrintf(0.5f)    0
lrintf(-0.5f)   0
lrint(0.5)      0
lrint(-0.5)     0
