#ifndef GREENLET_MSVC_COMPAT_HPP

/*
 * 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.
