At least StormC -- the statement was made based on all the code I've
resourced in the past, here I frequently saw the two commands, and
actually this was often a good indication of wether the code was
written in C or assembler... apparently things have changed...

All library calls use register args. One disaster is that there's a
stub for StackSwap in amiga.lib, and using this will definitely make
your program crash -- but this will only be used if you ommit the
proper exec-includes.
