Description
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.
