As far as I known on Windows 10 and above one can enable case-sensitivity 
for given folders. If one uses WSL, then it's default on and true for all 
subfolders as well. On MacOS one can create case-sensitive volumes.

So if someone wants to develop Linux kernel on these systems, with a 
little effort, one can create the proper environment for it including the 
case-sensitive directory structure/filesystem.

In my opinion merging the match/target files and thus shrinking the code, 
saving memory are more interesting in your efforts than your original goal 
- without sprinkling the code with warnings in pragmas.
