New submission from Stephen Kelly <[email protected]>:
When using C++ to extend python, one may use PyGetSetDef for example:
static PyGetSetDef Noddy_getseters[] = {
{"first",
(getter)Noddy_getfirst, (setter)Noddy_setfirst,
"first name",
NULL},
{"last",
(getter)Noddy_getlast, (setter)Noddy_setlast,
"last name",
NULL},
{NULL} /* Sentinel */
};
However, in C++ implicit conversion from const char* to char* is deprecated
since C++98, and is a removed conversion in C++11.

GCC/Clang warn about this, and MSVC in conformance mode (/permissive-) errors
on it.
PyGetSetDef and similar APIs should use const char* instead of char* for
members such as `name`.
