C does not specify the signedness of char.  If you care, you need to
explicitly specify.
Sorry, I didn't know this. Anyway I would expect the same behaviour from
both host gcc and ppc_8xx-gcc. In this case host gcc is wrong. 
No, it is not wrong.  The  behaviour  is  just  not  defined  by  the
standard,  so  the compiler is free to do what he likes. Some systems
default to singend chars,  others  to  unsigned.  Both  is  perfectly
legal.

It is code that makes any such assumptions which is broken.

Best regards,
