Re: Bug#175921: patch: patch works on i386, fails on powerpc


Not sure if this is relevant or not.  The default under PPC Linux gcc is to 
have all char types be unsigned by default whereas on x86 Linux char types 
default to be signed (I believe).  (I belive PPC Linux is unique iin this 
default among Linux platforms)

Perhaps the code has someplaces where char is explictly assumed to be 

You can easily test this hypothesis by having someone on ppc Linux rebuild 
the patch binary with the following gcc option added:


And then re-run thetest case and see if now passes.  If so, simply changing 
the declaration of char to be signed char in the code is enough.
