This is used as a common ground to feed both ttypes values and the GNAT tree nodes for the standard floating point types. * set_targ.adb (Long_Double_Index): The index at which "long double" gets registered in the FPT_Mode_Table. This is useful to know whether we have a "long double" available at all and get at it's characteristics without having to search the FPT_Mode_Table when we need to decide which C type should be used as the basis for Long_Long_Float in Ada.
