When I try compiling anything in CodeWarrior, including all the same programs I get an error:
Error : illegal precompiled header version
MSL MacHeadersMach-O.h line 14 #include <MSLMacHeadersMacOSX>

I can't even find the file it refers to:

/*

#if __mwlinker__
#ifdef __cplusplus
#include <MSLMacHeadersMacOSX++>
#else
#include <MSLMacHeadersMacOSX>
#endif
#else
#ifdef __cplusplus
#include <MSLMacHeadersMach-O++>
#else
#include <MSLMacHeadersMach-O>
#endif
#endif

Any ideas on how to fix this? (CodeWarrior 8.1, OS X 10.1.5)
