Ok, so I guess the fix is to put in a version statement to redefine all those
constants that determine what branch is used, so that it's still correct in
64-bit precision.  Then, to get GDC working until its exp() function stops
sucking, maybe the GDC patches should set the flag to assume 64-bit precision
on GDC x64, since as you note, for all practical purposes it is only 64-bit.
