I can't reproduce that. With both Arduino 1.18 and Arduino 2.1.1 it compiles OK:

Sketch uses 27196 bytes (84%) of program storage space. Maximum is 32256 bytes.
Global variables use 242 bytes (11%) of dynamic memory, leaving 1806 bytes for local variables. Maximum is 2048 bytes.

The error message you quoted says that the variable had to be const which it is:

https://github.com/nickgammon/arduino_sketches/blob/master/Atmega_Board_Programmer/bootloader_atmega328.h

const byte atmega328_optiboot [] PROGMEM = {

Have you downloaded the latest version of the code from GitHub?

There are a number of such files. Since you are posting a bug report here on Github, I assumed you would have the latest code. I suggest downloading all the code again (from here).

There is something strange about your packed sketch file. When I extract these with WinRar they never show up anywhere in Windows 10? Looked in older 1.8.12 and also in Arduino 2.1.

I don't know why you are using WinRar. They aren't RAR files. They are ZIP files which Windows 10 should easily be able to open natively. It is a very common format. See screenshot:
