Checking for the dll itself is not very useful, the tests won't be run if it's unavailable. Also are there platforms where `GetFontFallbackLanguageList` is missing?
Okay. I've removed the DLL check. bcp47langs.dll is not available on Windows 8 and older versions.

The other question is which versions have bcp47langs.dll but not GetFontFallbackLanguageList?

Probably none. Why? Isn't it possible that the test can be manually launched on Win7?

If there's no version that doesn't have the function, then you can import it directly and avoid all the extra work.
The behavior of the test on platforms that don't have the dll is irrelevant, there's no need to make any efforts to make the test succeed in that case.
