If you are referring to things such as _d_throw, _d_throwc,
_d_throwdwarf, others... In most cases, GDC has always done things in
the way that works for it, and as a result has almost never changed
ABI of library functions that it is tied to.  So we just have the one
_d_throw function for throwing dwarf EH, while DMD has gone through
several iterations over the years before finding themselves doing
things the same way as GDC - by which point you've given the function
a different name.  ;-)
