The system C library on Mac OS X 10.2 and below does not support
unicode: in other words all wide-character functions such as towupper et
al. do simply not exist so we need to provide our own in that context,
except for the wchar_t definition/typedef itself.
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.
