970 # the exceptional possibilities we have left ourselves with are ONLY overflow
971 # and inexact. and, the inexact is such that overflow occurred and was disabled
989 # overflow is enabled AND overflow, of course, occurred. so, we have the EXOP

4185 # no exception that was enabled was set BUT if we got an exact overflow
4186 # and overflow wasn't enabled but inexact was (yech!) then this is
4204 # the enabled exception was inexact. so, if it occurs with an overflow
4205 # or underflow that was disabled, then we have to force an overflow or
4206 # underflow frame. the eventual overflow or underflow handler will see that
4229 # insert an overflow frame
