We use a compilation symbol in our build to allow the inclusion of specific headers while building GTK, to avoid the need to include only the global header. Each namespace has its own compilation symbol because we used to have different libraries, and strict symbol visibility between libraries; now that we have a single library, and we can use private symbols across namespaces while building GTK, we should have a single compilation symbol, and simplify the build rules.
