[Mesa-dev] [PATCH 3/4] configure.ac: warn when declarations follow code

[Jose Fonseca]

Several components are never expected to be built with MSVC (glx, most dri drivers), so this would put (most likely undesired) burden on those maintainers.

I suspect we'll need to do this on a per directory basis...
