Re: [PATCH v2 0/1] MR1219: ntdll: Fix building on Mojave / Xcode 11.3.1.

[Stefan Dösinger (＠stefan)]

The `_STRUCT_X86_THREAD_FULL_STATE64` definition comes from `/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/include/mach/i386/_structs.h` . It does not contain `_STRUCT_MCONTEXT64_FULL` or `_STRUCT_MCONTEXT_AVX64_FULL`.

There is a usr/include/i386/_mcontext.h file in 10.14.sdk, but it doesn't contain any of these definitions, unlike its cousins in later SDK versions.
