27	unsigned-c-string does not work as advertised	sjamaan	felix winkelmann	"When trying to call a foreign C function that accepts ""unsigned char *"" arguments, I get compiler warnings ""pointer targets in passing argument N of 'X' differ in signedness"".

This is caused because unsigned-c-string(*) results in the same generated code as c-string(*). This happens on Chicken 4 and also on the current version of Chicken 3."	defect	closed	minor		compiler		fixed	ffi, unsigned, strings
