closes bpo-39605: Fix some casts to not cast away const. (GH-18453)
gcc -Wcast-qual turns up a number of instances of casting away constness of pointers. Some of these can be safely modified, by either: Adding the const to the type cast, as in: - return _PyUnicode_FromUCS1((unsigned char*)s, size); + return _PyUnicode_FromUCS1((const unsigned char*)s, size); or, Removing the cast entirely, because it's not necessary (but probably was at one time), as in: - PyDTrace_FUNCTION_ENTRY((char *)filename, (char *)funcname, lineno); + PyDTrace_FUNCTION_ENTRY(filename, funcname, lineno); These changes will not change code, but they will make it much easier to check for errors in consts
