[Bug c/13734] New: round() gives random numbers

["unruh at physics dot ubc dot ca" <gcc-bugzilla at gcc dot gnu dot org>]

The round() function outputs random numbers

#include <math.h>
main()
{
printf( "%f %f\n", round(1.0), round(1.0001));
}

Output
-2.000000 6.000000

However these values appear to be random, and can change on different 
machines and at different times on the same machine.

(Mandrake 9.0 and 9.1)
gcc -o test test.c -lm
