I checked both, and they are available, so I think we should guard the
definition like this:
// Provide a definition for _DISPATCHER_CONTEXT for Win7 and earlier SDK
versions.
// Mingw64 has always provided this struct.
#if defined(_LIBUNWIND_SUPPORT_SEH_UNWIND) && !defined(__MINGW64__) &&
defined(WINVER) && WINVER < _WIN32_WINNT_WIN8
# if defined(__x86_64__)
typedef struct _DISPATCHER_CONTEXT { ... } DISPATCHER_CONTEXT;
# elif defined(__arm__)
typedef struct _DISPATCHER_CONTEXT { ... } DISPATCHER_CONTEXT;
# endif
#endif
Does that seem right? I'm not super familiar with SDK version detection, so I
might have the wrong macros.
