[Openmp-dev] anonymous structs are a GNU extension

[C Bergström]

I don't like this patch - Using one compiler specific extension to
silence another compiler specific extension doesn't make sense to me.
While compilers that don't support this will probably ignore it, it
doesn't actual solve the problem.

If you really don't want the warning for clang - I think there's a way
in the cmake build to pass a clang specific flag to silence it.

Thanks
