Are you using MPW with the CodeWarrior 5 headers? Maybe using MPW's headers
would fix this problem.

FYI, cstdio is the C++ name of stdio.h. I think stdio.h #includes cstdio.

SIOUX.PPC.LIB. You might be able to hack it with the following global in
your code:

FILE __files[3];

My thoughts exactly. As I said before, probally better not to use
CodeWarrior headers in MPW. If you do use CW headers, don't link with any
MPW libs, use the MPW libs CW provides.
