Subject: [PATCH] Replaced the use of isspace() with our own version instead
 since we have most data as 'char *' and that makes us pass in negative values
 if there is 8bit data in the string. Changing to unsigned causes too much
 warnings or too many required typecasts to the normal string functions.
