The system C library on Mac OS X 10.2 and below does not support

al. do simply not exist so we need to provide our own in that context,

We need to do this for both project builder and CodeWarrior as
the latter uses the system C library in Mach builds for wide character
support, which as mentioned does not exist on 10.2 and below.
