Yes, this option might help me, but not the code which make assumtions
which are not garantees given by the ANSI C specification.  :)

I believe C99 specifies that char always should be signed, but not all
compilers follow the latest ANSI C standard yet.  Which brings me back
to my recommondation about using uint8_t which are well specified in
all ANSI C specs.
