My replies were not advocating for the C pre-processor. They were 
just to make sure people are aware of the pain we who write 
bindings to C libraries need to suffer in order to do it right...

In general, configuration management with D is terrible because 
DOD (D gOD) thought `version` is enough, and then you see code 
which first turns version(s) into enum(s), and then you see tons 
of static ifs in the code.

This is probably one of the reasons why Rust people are rewriting 
everything in Rust. Dealing with C libraries that have part of 
the "API" in header files as insane macros, and part in the 
actual library (static or dynamic) is no fun.
