Subject: cygwin fix : use unsigned char for ctype function

See http://www.nabble.com/-PATCH-RFA--Distinguish-between-EOF-and-character-with-value-0xff-td23161772.html#a23188494

cygwin 1.7 actually displays a warning when using signed char with the ctype
function, so that compilation fails when using -Wall -Werror.

So we just cast all arguments to unsigned char.
