This is test for MS-specific _stprintf() function. All test variants passes
also when compiled with MSVC compiler and run under msvcrt or UCRT runtime.
Note that gcc throws sprintf format warning for %hs usage in this test.
It is because gcc thinks that %hs takes unsigned short* argument.
But this is incorrect expectation, as all msvcrt and UCRT runtime versions
expect char* argument for %hs format. So this gcc format warning for %hs is
a gcc's bug.
