Comment(by mwanner):

 An 'int' return value gets casted to 'char' in several places. The latter
 isn't necessarily signed, so a '(int) -1' value may well be converted to a
 positive 'char' value on architectures where 'char' is unsigned.

 The attached patch fixes this issue by clearly separating the 'int' and
 'char' (or 'bool') values.
