Fails to compile with the latest MSVC 2019 x64 and C11 (C99 is OK)

[HappySeaFox]

Hi! Thanks for the great library!

With the latest MSVC (Community) update munit fails to compile when the C standard version is set to C11. With C99 it works fine. C11 used to work fine before the update.

CMakeLists.txt:

cmake_minimum_required(VERSION 3.10)

project(MUNIT-TEST VERSION 1.0.0
             LANGUAGES C)

set(CMAKE_C_STANDARD 11) # HERE
set(CMAKE_C_EXTENSIONS OFF)

add_executable(munit-test munit.c main.c)

main.c:

#include "munit.h"

int main(int argc, char *argv[])
{
    return 0;
}

outsider comment:
some of those errors look like MSVC doesn't like MUNIT_ARRAY_PARAM. i'm not sure why the _Thread_local complaints are there, though.
