+ * Support for MSVC on Windows.
+ *
+ * Beginning with Python 3.14, some of the internal
+ * include files we need are not compatible with MSVC
+ * in C++ mode:
+ *
+ *   internal\pycore_stackref.h(253): error C4576: a parenthesized type
+ *    followed by an initializer list is a non-standard explicit type conversion syntax
+ *
+ * This file is included from ``internal/pycore_interpframe.h``, which
+ * we need for the ``_PyFrame_IsIncomplete`` API.
+ *
+ * Unfortunately, that API is a ``static inline`` function, as are a
+ * bunch of the functions it calls. The only solution seems to be to
+ * copy those definitions and the supporting inline functions here.
+ *
+ * Now, this makes us VERY fragile to changes in those functions. Because
+ * they're internal and static, the CPython devs might feel free to change
+ * them in even minor versions, meaning that we could runtime link and load,
+ * but still crash. We have that problem on all platforms though. It's just worse
+ * here because we have to keep copying the updated definitions.
