(Since C doesn't have namespaces, we have to draw these borders within the identifiers themselves.) Even if you haven no clash now with __celltype, you could have one tomorrow, when you include some header that you did not previously include, port your program to a different system, or upgrade (or downgrade) to a different version of the compiler or any of your libraries, etc.
