[PATCH 16/16] build: enable vla warnings on Windows built code

[Morten Brørup]

> MSVC does not support optional C11 VLAs. When building for Windows

Minor detail, doesn't affect my Ack for the series...

Applications built for Windows with mingw and clang might use VLAs in the application itself.

Perhaps we should let them continue doing that for now.
