I'm not involved in the project, but your report is invalid.

This is a C file. delete is not a keyword in C. You appear to be compiling this code in C++. That's between you and your build system. If one wishes to name variables or functions in C as 'new', 'delete', 'operator', 'namespace', 'override', 'consteval' or other tokens that are keywords in C++ but aren't in C, that's totally legal. Doing that when building in C++ is, of course, prohibited.

I'd suggest closing this. The project is clearly abandoned, and your request is not really (strictly) an issue in code. It's in your build system. FWIW, LittleFS is usually a drop-in replacement, and it's actively maintained. Migration of installed systems is, of course, a pain.
