Dean,
I went ahead and copied "ansi.h" from:
/Developer/SDKs/MacOSX10.2.8.sdk/usr/include/ppc/ansi.h
to:
/Developer/SDKs/MacOSX10.2.8.sdk/System/Library/Frameworks/Kernel.framework/
Headers/ppc/ansi.h
I compiled against the 10.2.8 SDK and it compiled without errors! I then did
a kextload onto a 10.3.9 system and the kext loaded and ran fine. I haven't
tested loading it on 10.2.8 but I suspect it will run fine there as well.
So it appears that the Xcode 2.0 compiler not finding the ppc/ansi.h file
may be the problem.
