improve prog.c and try.sh for 2024/kurdyukov4

We improve `prog.c` beyond the 4M byte patch to reach 64M bytes.

The `try.sh` is made more robust, detecting both compiler and
executable problems that are **NOT** bugs in the code.

The code is now declared **INABIAF - please DO NOT fix**.
A detailed description of compiler, linker and resource
issues has been added to the `README.md` and `index.html`.
