Building with x86_64, I see two dmd flow control differences from x86 32
bit, which is odd.
std/math.d(1958): Error: function std.math.IeeeFlags.getIeeeFlags has no
return statement, but is expected to return a value of type uint
std/math.d(2162): Warning: statement is not reachable
The first part looks legit. DMD 32 should have detected that one.
The second part looks bogus. DMD 64 isn't handling that right.
This fixes both, but...
