There is a misunderstanding here. Alex is talking about UnixLib at
gccsdk/trunk/gcc/unixlib which is upcoming v5.0 and has all Norcroft
specifics removed as this version will become ELF only and be of no use
for Norcroft builds.
Version 4.3 is pretty old and part of the 3.4.5 Release 1. I'm fairly
use that this is Norcroft compatible with the understanding that you have to
use Norcroft to build UnixLib. The reason is that APCS-32 for GCC and
Norcroft is not 100% compatible (float/double argument passing) and that
when you are using GCC it might require additional routines which are
provided by libgcc library.
