 The message comes from these lines in `../include/libEMF/wine/winnt.h`:

 {{{

    31   /* These are hardcoded to avoid dependencies on config.h in

 }}}

 All architectures are lower case, except PowerPC! And GCC 4.2 #defines:

 {{{
 #define _ARCH_PPC 1
 #define _ARCH_PPCGR 1
 define __ppc__ 1
 #define __POWERPC__ 1
 }}}

 So we have an easy patch for this case! (Presumingly.)
