ccstruct: Fix compiler warning (disable buggy code)

Browse Source 
gcc reports a potential bad array access:

ccstruct/mod128.cpp:98:20: warning:
 array subscript has type 'char' [-Wchar-subscripts]

dir is of type 'char'. Most compilers use signed char by default.
Then the value of dir is in the range -128 ... 127 and cannot be
used to access an array with 256 elements.

Don't fix that but disable the buggy code.
