Ah, you're right, thank you. It's the 5.3.0 manual that mentions the 
flonum fallback, even though csc 5.3.0 generates C_int64_to_num just 
like git-head.


I got confused by building 4 chicken versions (git-head / 5.3.0 + gcc-12 
/ llvm17), trying to chase down the performance problems I mentioned in 
the "csi slow" thread. It wasn't any of that; at this point it *seems* 
to be building with C_COMPILER_OPTIMIZATION_OPTIONS set to 
-march=native. This flag (maybe any flags, I don't know yet) not only 
make csi but also csc output twice as slow for my program, for all 4 CC 
/ chicken-version combos (on my platform, CPU etc -- I'll write more in 
the other thread).
