Sun Studio on Solaris issues warnings about improper initialization values being used when defining tolower_trans_tbl[] in ctype.c. The array wants to store values with high-bit set and treat them as values between 128 to 255. Unlike the rest of the Git codebase where we explicitly specify 'unsigned char' for such variables and arrays, however, kwset code we borrowed from elsewhere uses 'char' for this and other variables. Fix the declarations to explicitly use 'unsigned char' where necessary to bring it in line with the rest of the Git.
