Don Lewis b049eba905 Fix type for abs() calls in net/opal ... During the exp-run in bug 208158, it was found that net/opal gives errors with libc++ 3.8.0 [1]: ../common/mpi.cxx:135:18: error: call to 'abs' is ambiguous distance = ( abs(MPIs[i].width - desiredWidth ) * ^~~ This is because abs() is being called with unsigned arguments. Fix this by casting the arguments to the appropriate signed type. This mimics what happens with older libraries where the only version of abs() was the one in <stdlib.h>, which is prototyped: int abs(int) Correct functioning of this expression relies on how integer overflow actually behaves, which is actually undefined in the C++ standard.
