PyMemberDef from Noddy examaple: https://docs.python.org/3/extending/newtypes.html

static PyMemberDef Noddy_members[] = {
    {"first", T_OBJECT_EX, offsetof(Noddy, first), 0,
     "first name"},
    {"last", T_OBJECT_EX, offsetof(Noddy, last), 0,
     "last name"},
    {"number", T_INT, offsetof(Noddy, number), 0,
     "noddy number"},
    {NULL}  /* Sentinel */
};

When compiling the code with the PyMemberDef above with GCC, it compiles well. However, with G++, ISO C++11 complains(warns) it is deprecated to convert string literal to 'char *' is deprecated [-Wc++11-compat-deprecated-writable-strings]

Should the example code be fixed, or should PyMemberDef fixed? I think PyMemberDef.name should bo const char * instead of char *.

PyMemberDef.name already is "const char *" in 3.7 (see issue28761).

Adding the const qualifier in other branches can break existing code that assigns PyMemberDef.name to a variable of type "char *". This is not appropriate for bugfix releases.
